Sparks, MD—Brimrose Technology Corporation’s BioTech Division has received an award to develop rapid tests for U.S. soldiers to protect them against the plague. The kits will provide a level of protection for U.S. soldiers as they increasingly are being stationed in Africa. The award was approved by the U.S. Defense Threat Reduction Agency (DTRA) and is being contract managed by Advanced Technology International (ATI) representing the Medical CBRN Defense Consortium (MCDC).

The goal of the program is to develop a field kit that can be used on soldiers by field medics without having to wait for laboratory analysis, which is currently required. A total of 500 kits will be produced for pre-clinical evaluation in the first phase.

If successful, including approval from the U.S. Food and Drug Administration, the team will move to the second phase of the project which will entail human testing. The program could ultimately lead to thousands of such kits being manufactured on an annual basis for U.S. soldiers and other in-field personnel.

“This is the first Point of Care rapid test for plague that will be submitted for use under FDA 510K,” according to Dave Trudil, director of BTC’s Biotech division. (For more information, contact David Trudil at 410-472-2600 or send email to office1@brimrosetechnology.com.)

Sparks, MD—The U.S. Department of Energy has awarded Brimrose Technology a Phase 1 Small Business Innovation Research (SBIR) award to improve the manufacturing of small modular reactors by means of non-destructive testing. Penn State University is a subcontractor on the award.

The focus of the Phase I portion of the award is to demonstrate the feasibility of an ultrasonic scattering technique (UST) used to characterize the microstructure and material properties for components made with various additive manufacturing characteristics. The testing will serve to determine whether heat treatment and/or additional processing is necessary.

Gaining this understanding will lead to laying the groundwork for optimizing the process monitoring for large-scale inspections that will then lead to better component reliability, according to Brimrose Tech.

By the end of Phase I, components made with various process parameters will be tested using the UST process, which will then be validated by using traditional destructive testing.

For Phase II, BTC will focus on refining the electronics and data-processing algorithms in the prototype, optimizing the sensitivity, and testing components of different types and power sources.

Dr. Chen Chia Wang is the Brimrose Tech Principal Investigator. The Phase I award is for $149,995 (For more information, contact David Chaffee at 410-472-2600 or email office1@brimrosetechnology.com.)

Sparks, MD—An Acousto-Optic Modulator (AOM) made by the Brimrose Corporation of America is now being implemented by NASA as part of a new facility known as the Cold Atom Laboratory (CAL) on the International Space Station (ISS).

“We are delighted that our acousto-optic modulator was selected by NASA for this important mission,” said Dr. Jolanta Soos, Brimrose’s Chief Technology Officer. “It is another example of how we customize our A-O devices for various applications so that they can be used throughout the world and on into space.” (A photo of the modulator is included at the end of this press release.)

The Cold Atom Laboratory was developed at NASA’s Jet Propulsion Laboratory and already has begun operating on the ISS. It will provide scientists with an improved set of tools for probing the realm of quantum mechanics, which is the study of nature at the very smallest scale.

The AOM is considered to be the key component inside CAL for manipulating the atoms for interferometry, according to James Kellogg, CAL Engineer of Lasers and Optics at the Jet Propulsion Lab. It is a fiber-coupled, solid-state device that can tune laser light to very specific frequencies while switching on and off in less than 100 nanoseconds. Brimrose also makes a free space version of the AOM.

The CAL facility will produce clouds of ultra-cooled atoms called Bose-Einstein Condensates (BEC). These are chilled to a fraction of a degree above absolute zero, or even colder than the average temperature of deep space. The atoms in a BEC demonstrate quantum characteristics at relatively large-size scales, allowing researchers to explore this strange domain with greater understanding.

To reach these ultra-cold temperatures, the CAL uses a three-step process. First, lasers are used to corral the atoms and slow them down, stealing their energy and reducing the temperature to approximately 100 microKelvin. This step is completed with a device called a magneto-optical trap. The cooled atoms are then help in a “magnetic trap” that causes the warmest atoms in the cloud to separate from the cooler atoms; radio waves then push the warm atoms away, reducing the cloud’s overall temperature to less than 1 microKelvin. Thirdly, the cloud’s natural expansion causes the temperature to drop further (this is called adiabatic expansion) into the 100 picoKelvin range.

In one year, the CAL instrument is expected to be fitted by astronauts with a new atom trapping cell that is currently being designed to deliver the AOM light pulses to the atoms.

Brimrose has been making A-O Modulators and related components for more than 30 years. The modulators are used to control laser beam intensity, frequency modulation, frequency shifting, to control pulses and more. The AOMs are offered with conduction and water-cooled enclosures. Brimrose AOMs are offered from the ultraviolet to LWIR wavelength ranges for low and high optical power applications. They cover frequency ranges from just a few MHz up to 3.5 GHz. (For more information, call 410-472-2600).

Below is a fiber-coupled version of the A-O Modulator:

Sparks, MD—The Brimrose Technology Corporation (BTC) has received major additional Sequential Phase II program funding for three critical SBIR/STTR programs aimed at protecting military personnel and first responders going into potentially hazardous areas.

The U.S. Army base at the Edgewood Chemical and Biological Center (ECBC) at the Aberdeen Proving Ground has added significant funds to the programs for the purposes of developing better detectors to identify chemical and biological agents from a distance through Laser Induced Thermal Emissions (LITE), to do the same deploying Long Wavelength IR (LWIR) spectropolarimetry, and by using quantum dots to more fully develop low cost infrared cameras to help in this detection processes. The LITE program is an STTR, while the other two are SBIRs.

“The U.S. Army is constantly trying to improve the technology that will help our troops better understand the nature of the environments they are being exposed to,” said Dr. Sudhir Trivedi, BTC’s Director of R&D. “We believe the technology being developed will help our warfighters and first responders to do just that.”

Using Laser Induced Breakdown Spectroscopy (LIBS) processes, Brimrose scientists have developed a newer process known as Laser Induced Thermal Emissions, or LITE, to identify molecular signatures as well as the constituents commonly associated with LIBS.

The plus-up focuses on the development of improved detectors to identify the molecules produced by laser pulses. The importance of this work cannot be overstated. For example, while LIBS might provide the operator in a potentially hazardous zone with the understanding that carbon, hydrogen, nitrogen and oxygen atoms are present, which may be seem harmless, LITE can provide the ingredients that would show that toxic compounds are in the area composed of these elements.

The proposed LIBS/LITE program could also further improve the standoff distance at which instruments can identify such materials at up to 30m, which is important to the safety of those going into such hazardous areas, as well as improve the efficacy and ruggedness of the design.

The goal of the AOTF-based spectro-polarimetric imaging system program is also to detect chemicals at a distance in a hazardous zone using a long-wavelength IR (LWIR) hyperspectral spectro-polarimetric imaging sensor. The goal here also is to improve the sensor to provide for standoff distances of up to five km. BTC also believes there are significant commercial applications for this product in atmospheric remote sensing and medical diagnostic applications.

Regarding the use of quantum dots, BTC already has produced a SWIR FPA (short wavelength infrared focal plane array) camera, in collaboration with Research Triangle Institute, NC, with a resolution of 640 x 512 pixels and a sensitivity from 0.4 mm to 1.7 mm at room temperature. The goal is to continue to extend the operational wavelength range to 2.5 mm, and then 3.0 mm. BTC says the CQD-based SWIR FPA proposed would be on the order of 6-7 times less expensive, and would greatly enhance its utility. One application of the camera would be to aid the LIBS/LITE and spectro-polarimetric systems by developing cameras with extended ranges.

Sparks, MD—The Binational Industrial Research and Development (BIRD) Foundation, a program funded by the U.S. and Israeli governments, has awarded Brimrose Corporation and Israeli partner File X an $800,000 two-year grant to develop a new generation of hyperspectral imagers. One potential application is identifying oil spills in the ocean.

The joint program, entitled "Real-Time AOTF-based Hyperspectral Imaging System for Pollution Detection," relies heavily on foundational technology Brimrose has developed over the years using its Acousto-Optic Tunable Filter (AOTF) technology, which offers incredibly fast wavelength scanning speeds of up to 16,000 wavelengths per second, yet has the ability to precisely focus in on one wavelength.

File X, based in Ness Ziona, Israel, is providing advanced software for the project, which will allow the new instrument to match the real-time wavelength image with images from a data base built into it.

Oil pollution is an enormous global problem. The ability to rapidly identify an oil spill, and then quickly contain it, is critical. This is a primary goal of the unit being developed for the program.

There are some 20,000 oil spills reported in the United States alone on an annual basis, according to the International Tanker Owners Pollution Federation. An estimated 1.3 million gallons of oil are spilled into U.S. waters annually, according to the U.S. Department of Energy. Cleanup costs, especially in those areas where oil spills are not identified and contained rapidly, run into the billions of dollars. Estimates for the cleanup for the BP oil spill in Louisiana were as high as $12.5 billion.

The award was highlighted as part of a recent trip by Maryland Governor Larry Hogan to Israel. David Trudil, who directs Brimrose’s Biotech Division, was a member of the delegation.

Sparks, MD--Fresh off a major award from the BIRD Foundation, Brimrose joined the recent trade mission led by Maryland Governor Larry Hogan to Israel. The governor’s purpose was to increase trade and business with Israel.

"We are excited that Maryland-based Brimrose Corporation has been named a partner in a major US-Israel Binational Industrial R&D Foundation (BIRD) award," said Maryland Governor Larry Hogan. "It’s just this kind of collaboration between Maryland and Israeli companies that was at the center of my recent trade mission."

David Trudil, who directs Brimrose’s Biotech Division, was a member of the delegation. Trudil was involved with the Brimrose effort to obtain the BIRD Foundation award.

The week-long trip involved a delegation of some 35 Maryland business leaders, academics and state officials. A number of agreements between Maryland-based institutions and Israeli organizations were signed.

Sparks, MD—Brimrose Technology Corp. (BTC) has been awarded nearly $150,000 to develop a new group of mercurous iodide materials for the purpose of helping the high-speed, high spatial resolution detection of X-Ray Imaging.

The U.S. Defense Threat Reduction Agency (DTRA) made the award, which formally started earlier this week. BTC’s Dr. Sudhir Trivedi, the company’s Director of Research and Development, is the principal investigator on the award.

“Despite years of research, no explored candidate can well satisfy both the demands on spatial resolution at the micron level, and the requirement on real time and time resolved data at a high speed/frame rate, at the same time,” said Dr. Trivedi. “Our proposed Hg2I2 sensor can effectively provide the answer to this call.”

The focus of the work will be on both the material engineering aspect of the material itself which includes crystal growth—BTC has its own crystal growth laboratory--along with fine-pitch pixel device fabrication development, x-ray response measurement, as well as theoretical modeling/calculation to demonstrate its feasibility of meeting or exceeding the desired specification.

Both the government and commercial markets could greatly benefit from this semiconductor sensor, according to the proposal. When coupled with advanced CMOS-ASIC technology, the results can be applied to the identification and collection of data related to deeply buried targets in support of DTRA’s Counter-WMD/CBRNE missions. Such enhanced detection also has potential application to locate “dirty bombs” entering or inside the United States prior to detonation.

NASA could also benefit from use of these new detectors in understanding the surface and sub-surface compositions of planetary bodies.

The medical community may also benefit from the enhan.ced ability of large medical detection machines such as SPECT, PET and Spectral-CT to detect cancer at a very early stage, including breast cancer in women.

BTC is the research laboratory of the Brimrose Corporation of America, a high-tech company involved in advanced materials development, AO components, near IR spectrometers, as well as high-tech solutions for the U.S. military and NASA. For more information, call 410-472-2600.

Sparks, MD--Announced only a few short months ago, Brimrose Technology’s Biotech division already has begun offering multiple products as it rapidly grows into the accelerating biotech marketplace.

“Biotech already is becoming a critical element of Brimrose Technology,” said Founder and CEO Dr. Ron Rosemeier. “We are forging ahead on multiple levels, integrating our existing technology where appropriate, using what our partners are providing, and creating new technology where it makes sense.”

Brimrose Technology now is offering tunable light sources operating in the 450-650 nm wavelength range and include both the VIS and SWIR regions. The units, which include pre-aligned lamps, can be used for fluourescence and microscopy applications, as well as a component in spectroscopy. This product is now commercially available and is already being used in research medical applications.

The division also now is offering what we believe are the best bacteriophage products in the world, thanks to our partnership with the Eliava Institute in the country of Georgia. The phages we are now offering include Pyo, Fersisi, SES, Staphylococcal, Intesti and Enkophagum.

Dave Trudil, who directs the Biotech Division, has served as the critical link between Eliava and Brimrose Technology regarding the bacteriophage materials. “With the over-proliferation of antibiotics in our world, we are looking at bacteriophage materials as an important, natural alternative,” according to Trudil. To order or for more information call 410-472-2600.

Brimrose Technology is a high-tech company involved in acousto-optic components for R&D applications as well as advanced materials solutions for the U.S. government and other institutions. It has generated more than $120 million in contracts throughout its history.

Sparks, MD—NASA has selected Brimrose Technology Corp. (BTC) to provide sensor systems using Raman technology for future planetary exploration. The technology has other potential applications, as well.

BTC is teaming with North Carolina State University as part of a Phase I Small Business Innovation Research award valued at $125,000.

The proposed method and rugged instrument will be able to provide fast material identification regarding its molecular composition during planetary and asteroidal exploration missions.

Brimrose Tech has a rich history of working with NASA on planetary exploration. Brimrose’s hyperspectral imager was highlighted in NASA’s recently issued annual NASA Spinoff 2016, The goal there was to use Brimrose’s highly intelligent acousto-optic tunable filter technology for Mars composition evaluation.

The goal of this contract, entitled “Compact Raman Spectrometer for In-Situ Planetary Chemistry,” is to demonstrate a new Raman imaging sensor based on a compact, CCD-mounted spectrometer. This enables high sensitivity and specificity for UV-Raman that will be capable of full-frame imaging, thus reducing size, weight, and power requirements, as well as eliminating the need for mechanical scanning and actuators to acquire data across a two-dimensional image.

The proposal team, which was led by BTC Senior Scientist Dr. Feng Jin, suggests the technology also has a significant number of potential non-NASA applications, including: chemical and explosive detection and identification; non-destructive detection/evaluation; pharmaceutical composition analysis; counterfeit detection; compound distribution; powder content and purity; polymorphic forms identification; and contaminant detection and identification; Medical applications include DNA/RNA analysis, drug/cell interactions study, and single cell analysis. Gemstone and mineral identification represents another potential application.

Brimrose Technology is a high-tech company involved in advanced materials solutions for the U.S. government and other institutions. It has generated more than $120 million in contracts throughout its history and technology developed here has been used for commercial products by sister company Brimrose Corporation of America.

Sparks, MD--Brimrose Technology Corp. (BTC) is excited to announce the unveiling of a new sector, our Biotechnology Division. This opens a new discipline of business for BTC, one which also brings us a strong presence into the life sciences.

To prepare for our new division, BTC has been working with world-class biotech institutes and hiring qualified new staff. BTC is working with a variety of globally recognized institutes and companies, including the Eliava Institute in Tbilisi, Georgia; the Jiangsu Academy of Agricultural Sciences in Nanjing, China; NHDetect, Baltimore; and the International Phage Research Center.

David Trudil has joined Brimrose to help coordinate efforts with NHDetect, a company he directs, and New Horizons Diagnostics Corp., a Maryland-based company which specializes in manufacturing tests for the rapid detection of bacteria and toxins in human, environmental, surface, food, and water samples for use by municipal and corporate customers. The company also works with local and national governmental agencies.

Dr. Yingyun Liu, who has joined the Biotechnology Division to work on the application and detection of lytic enzymes. Like Trudil, Dr. Liu is also playing an important role in coordinating efforts with New Horizons Diagnostics Corporation. He received his Ph.D. from Penn State University, after prior study in China.

One focus of research is on the utilization of the bacteriophage virus and Phage Lytic Enzymes for the treatment, prevention, control and detection of specific bacteria in the environment or in applications for agriculture, animal or food use. Bacteriophages, or bacteria eaters, occur in nature, kill bad bacteria, are safe for animals, are inexpensive, and do not harm the environment or cause the problems that antibiotics do. While bacteriophages have been used for some time with varying degrees of success, work by Trudil, the aforementioned Georgian and Chinese institutes, and other researchers working with Brimrose show significant progress and should lead to greater use of these important viruses.

Working with the Eliava Institute, our new Biotechnology Division is offering a series of unique bacteriophage products which are being used to replace antibiotics in poultry feed and for other important applications. As mentioned, bacteriophages are “good” viruses that attack and kill bad bacteria that can harm poultry and other living things.

The new division also is working with partners on the development of Fluorescence Strips for the rapid and sensitive detection of bacteria, viruses and toxins based on immunological (antibody-antigen) reactions.

Sparks, MD--Brimrose Technology Corporation (BTC) has received a new Phase I SBIR (Small Business Innovation Research) grant from the United States Air Force regarding the use of new, advanced materials for enhanced radiation detection.

The company is receiving $148,872 to develop new halide materials which may be critically important to the new, second generation of radiation detection devices that are gradually replacing older, first-generation, scintillator-based detectors.

The new materials, developed under the leadership of Brimrose Technology’s Dr. Henry Chen, are considered rugged, portable, low cost and capable of detecting both gamma and neutron radiation.

“Our goal is to deliver a breakthrough in detector technology that can address most, if not all, of the limiting issues of current technologies, and thus effectively provide an answer to the call for advanced detectors from the U.S. Department of Defense and the U.S. Department of Homeland Security,” said Chen.

Chen also is involved in brimRAD, a new spinoff company that Brimrose is developing that is focused on making a new generation of radiation detectors for the defense/security, medical and university/industrial markets. (For more information, go to www.brimrad.com)

This new award comes less than two months after Brimrose Technology received four SBIR awards, two of which were Phase I and two that were Phase II. Chen spearheaded one of those Phase I awards, also, which was provided by NASA.

While Brimrose Technology operates a very active and successful R&D program under the direction of Dr. Sudhir Trivedi, a program that has generated more than $100 million in R&D contracts during Brimrose’s 35-year history, the parent company generates 80 percent of its annual revenue from commercial products, which are based on the R&D work.

Sparks, MD—Long known for its research and development prowess, Brimrose Technology Corp. (BTC) has been awarded two Phase I and two Phase II Small Business Innovation Research (SBIR)/Small Business Technology Transfer (STTR) grants in a matter of weeks. The total amount is nearly $2 million.

Even by Brimrose Tech’s own high R&D standards—which have resulted in more than $100 million in federal contracts across its 30-year history—this is a major development. The company uses its R&D contracts to directly feed its strong product base. Eighty percent of Brimrose revenues come from product revenues.

“It is gratifying to know that the U.S. government sees this amount of value in Brimrose Technology research,” said Dr. Sudhir Trivedi, the director of R&D at BTC. “All of our customers, including the U.S. government, know that Brimrose will work hard to deliver what we say we will. These awards do not come in a vacuum. They are based on many years of successful collaborations and demonstrations and solid results.”

BTC has been awarded a Phase II STTR from the Missile Defense Agency at Redstone Arsenal in Alabama with BTC Senior Scientist Dr. Dajie Zhang acting as principal investigator. The objective is to demonstrate the feasibility of producing light weight and thermally manageable integrated optical systems suitable for airborne and space high power directed energy applications. This project will focus on improving two of the most important parts of a high energy mirror design, the highly reflective mirror surface, and the light weight and stiff multifunctional substrate. The award is for $999,477.00.

The company also has been awarded a Phase II STTR from NASA Langley Research Center for $749,494 for “Acousto-Optic Tunable Filter-Based Polarimetric Spectral Sensor with Progressive Algorithm for Material Analysis and Mapping.” Dr. Trivedi is the principal investigator. The STTR addresses the NASA Planetary Science Mission to advance scientific knowledge of the origin and history of the solar system and the potential for life elsewhere. The work expands on the AOTF-based SWIR spectropolarimetric imaging system developed in Phase I which will be further optimized and integrated with optimal algorithm/software in Phase II. BTC believes this will be a useful tool in determining the chemical composition and physical characteristics of planets of interest, short period comets, primitive meteorites and asteroid bodies, and in identifying the sources of simple chemicals important to prebiotic evolution and the emergence of life. The award is for $749,494.

NASA has awarded BTC a Phase I SBIR regarding “Novel Approach in Fabrication of Shielding Composite Materials by Emerging Field Assisted Sintering Technique.” The Principal Investigator is Dr. Trivedi. The objective is to develop a radiation shielding material system that is sufficiently strong to serve as a load-bearing structure. Such a materials system does not currently exist. The ideal shielding material for space applications should preferably be light weight with good mechanical strength and good thermal conductivity. BTC is proposing a novel approach to fabricate reinforced composite materials for radiation shielding applications using a powder metallurgy approach with sintering via the innovative Field Assisted Sintering Technology (FAST). The award is for $124,887.

NASA has awarded Brimrose Tech a Phase I STTR related to “Instrumentation for Multiple Radiation Detection Based on Novel Halides for Nuclear Planetology.” BTC is proposing a spectrometer that employs a single room temperature semiconductor detector that can perform both gamma and neutron spectroscopy. The proposed detector is based on novel halide materials. The halide materials are new wide band-gap semiconductor detector materials that can provide radiation detection with low cost, high performance and long term stability. BTC will be collaborating with Fisk University on this contract. The amount of the award is $124,859.

Sparks, MD—Brimrose Technology Corporation (BTC) staff members have received an important patent (US 8,830,316 B2) related to improved data capturing for military and security purposes. The research team was led by Brimrose Senior Engineer Dr. Feng Jin.

The patent, entitled Unattended Spatial Sensing, involves a low-cost, ground-based imaging sensor that can capture pixel data from a radiating target. The pixel data are sent to a remote location, where they are analyzed to fully identify the target.

“The patent involves a remote sensor and process for easily disseminating small data packages in a wireless or wired format,” said Dr. Sudhir Trivedi, Brimrose Technology Director of Research and one of the patent’s contributors. “The technology can also be used for detecting home invasion or for protecting commercial properties from unwanted intrusion.”

The patent was originally engineered to improve the capabilities of the company’s Unattended Ground Sensor (UGS) product, known as SPOT (Silhouette Profiling Optical Tripwire), which can identify targets in hostile environments using narrowband imaging.

Using SPOT, the electromagnetic radiation from the target is intercepted and sent to a remote command location via a communications system, often including a satellite. The detector array included in the patent improves the information-capturing capability of SPOT so that the person receiving the signals will better be able to discern exactly what the target is.

Sparks, MD—Brimrose Technology scientists are using the company’s extensive technology base in laser vibrometers for an important new application: the study of microcracking in gun and rifle barrels. Technologies are being developed at Brimrose that are capable of inspecting embedded defects in these and other metallic hollow cylinders.

The scientists note that the inspection of hollow metallic cylinders present two challenges: (1) the curvy surfaces of barrels and (2) the generally rough surface quality they possess. Curvy surfaces present great challenges to ultrasonic inspection technologies since it is quite difficult to achieve or maintain sufficiently good physical contact between the flat transducer surface and the cylinders. Laser-based inspection technologies suffer from the simple fact that optical speckles induced by the metallic surface create an insurmountable obstacle in achieving a constantly reliable and accurate assessment of the conditions of the metallic cylinder under investigation.

By using Brimrose’s proprietary pulsed laser vibrometer technology, the scientists can examine the hollow metallic cylinders by remotely sensing how the cylinder vibrates under given mechanical stimuli. They have discovered that the presence of a defect modifies the vibratory characteristics of the cylinder as slightly different modes are excited by the defect.

Brimrose Technology scientists further have discovered that by determining the minute spectral shifts, characteristic dimensions of the defect can be estimated. Localized variations in the vibratory signatures can further be utilized to determine the location of the defect. With the knowledge concerning the dimensions and locations of the defect, further actions can be assessed and taken to rectify the operational challenges facing the reliable and safe deployment of gun barrels.

Laser vibrometers are a core technology of Brimrose Technology’s and have been for more than two decades. Brimrose has used laser vibrometer technology successfully for a number of military programs, including vehicular weight monitoring, landmine detection, and trace molecule/explosives detection, among other things.

Sparks, MD—Brimrose Technology Corporation, the R&D arm of Brimrose Corporation, believes it is important to maintain a military presence and mindset at the company.

Brimrose regularly sends employees to the Storm Mountain Training Center facility in West Virginia to better experience and understand the conditions that exist for the soldiers it is designing equipment for.

“We believe this makes Brimrose unique as a small defense contractor,” said Brimrose CEO Ron Rosemeier. “Our scientists and engineers, men and women, go out into the field to train to better understand the environment they are making the equipment for.” Storm Mountain, located in Elk Garden, West Virginia, is run by Dr. Rod Ryan, a former Special Forces non-commissioned officer and policeman. The facility offers a variety of courses in handgun, rifle and sniper education. [www.stormmountain.com]

Storm Mountain also specializes in advanced urban sniper scenarios that potentially exist in real-world situations, including routing out suspected terrorists in buildings and at large events. Brimrose employees, who have attended classes extensively, stay abreast of the latest U.S. military measures and countermeasures, which in turn are engineered into Brimrose products for defense applications. It is only through this kind of experience that Dr. Rosemeier believes Brimrose employees can maintain the edge necessary to best provide the products required by American troops.

Throughout its history, Brimrose Technology has developed tools for the warfighter, largely via its hyperspectral imaging technology, but also including its advanced materials program. Today, the company is developing HERO (Heli Engagement Reconnaissance Observatory), its unattended aerial vehicle for military sensing and firepower; optical taggants—used for the identification of troops and materials in theater; and military vests for women.

“This is intense training that brings our people closer to the products they are making,” says Dr. Rosemeier. “It is critical for us to better understand in what environment our products are being deployed.”

For more information, call 410-472-2600.

Baltimore—Brimrose Technology engineers are concentrating on extending the distances the military can use to identify optical taggants in the field and have developed proprietary designs to that effect. Brimrose hyperspectral imagers can currently identify such taggants up to distances of 50 feet at night and up to 150 feet during the day. The company wants to increase those target identification distances to 2,000 feet.

Such distances would allow a helicopter pilot landing in a field to identify soldiers in the general area, for example, or make sure lethal force is used accurately in today’s increasingly complex, long-distance battlefield.

Brimrose already has put extensive resources into optical taggant development. The company is capable of identifying optical taggants outside of the near IR range common to most international defense operations. This means soldiers will remain protected from non-friendly governments but are identifiable using the optical taggants Brimrose makes.

“Hyperspectral imagers and their identification of optical taggants is becoming a fact of life in the modern battlefield of the 21st century,” says Dr. Ron Rosemeier, president and CEO of Brimrose. “We are trying very hard to keep the U.S. warfighter technologically ahead of his enemy.”

Optical taggants can be used to tag, track and locate objects, targets or soldiers by modulating certain wavelengths in the short-wave IR (SWIR).

Brimrose will be demonstrating its optical taggant identification capabilities at SPIE DSS this week. The company is located at Booth No. 957.

For more information about Brimrose Technology or our optical taggants’ program, call 410-472-2600.

Sparks, MD—Brimrose Technology Corporation (BTC) has received a Phase I STTR (Small Business Technology Transfer) award to develop a spectropolarimeter that will be capable of operating in the shortwave infrared. The amount of the award is $125,000.

The analysis of polarized light can help discriminate and classify materials and identify objects, which is important as the National Aeronautics and Space Administration (NASA) contemplates a series of landing missions to other planets, comets, asteroids and outer planet moons.

The measurement of the polarization state can also provide various characteristics such as surface properties, shape, shading and roughness, and can be used to identify unique features that will allow for more accurate discrimination between various materials than spectral data can by itself.

Brimrose will be working with UMBC (the University of Maryland at Baltimore County) as its university research partner on the award.

“Brimrose has a long history of helping NASA develop the tools and advanced materials necessary for NASA’s mission assignments,” according to Dr. Sudhir Trivedi, Brimrose’s Director of Research. “The development of the proposed full-scope spectropolarimeter will offer a dramatically improved optical solution for material analysis by performing fast spectral profile acquisition.”

The research suggests a rich potential for commercial applications both inside and outside of NASA.

For example, potential commercial NASA applications include material databasing, structural validation, use on missions for identification purposes, combustion spectroscopy, non-destructive testing of space-compliant parts, and qualification of time-sensitive materials in space.

Potential non-NASA commercial applications include anomaly detection, countermine research, camouflage concealment and detection, and identification and discrimination of friend vs foe using optical taggants in military applications. There are also applications for atmospheric monitoring and the potential for on-line processing and feedback control in pharmaceuticals, chemicals, pulp and paper, and biotechnology.

Sparks, MD—Brimrose Technology Corporation (BTC) has received a $150,000 Phase I STTR award from the U.S. Department of Energy Office of Science. The award relates to the use of next-generation, semiconductor-based radiation detectors using cadmium magnesium telluride (CdMgTe).

The focus of the award, which includes SRI International as the research institute partner, is to improve on existing materials used for radiation detection by developing the new CdMgTe materials. BTC has been developing advanced materials for over two decades and has extensive materials R&D tools at its Maryland facilities.

“This is another potentially significant step in the war on domestic and international terrorism,” said Brimrose CEO Dr. Ron Rosemeier. “The rapid detection of nuclear presence is becoming a critical fact of life in today’s world.”

The principal investigator is Dr. Sudhir Trivedi, Brimrose’s Director of Research. “We have identified several different advantages CdMgTe has over the existing material,” according to Dr. Trivedi. “We believe there is the potential for better charge transport properties, improved structural properties, and a higher potential yield, among other improvements.”

BTC is the research laboratory of the Brimrose Corporation of America, a high-tech company involved in advanced materials development, acousto-optic components, near IR spectrometers, and high-tech solutions for the U.S. military.

Sparks, MD - Brimrose Technology Corporation (BTC) has received two new Phase I STTR (Small Business Technology Transfer) awards.

DARPA has awarded Brimrose Technology an award for $100,000 for a proposal entitled "Narrow Band Gap Quantum Dots and Quantum Wires for Mid-Wave Infrared Focal Plane Array Detectors."

The DARPA proposal's objective is "to demonstrate the feasibility of producing quantum dot focal plane arrays for mid wavelength Infrared (MWIR) photodetectors." The study may extend the detection range into the long-wavelength Infrared (LWIR). RTI is a collaborator on the project.

"These photodetectors will find many uses both in military and civilian applications such as night vision, surveillance, IR countermeasures and IR spectrometers," according to Dr. Dajie David Zhang, a senior scientist at BTC and the DARPA STTR project’s principal investigator.

BTC also has received a new Phase I STTR from the U.S. Missile Defense Agency (MDA) focused on "Light Weight Optics for High Power Directed Energy Applications."

The objective of the MDA award is to demonstrate the feasibility of producing light weight and thermally manageable integrated optical systems suitable for airborne and space high power directed energy applications.

"This project will focus on improving two of the most important parts of a high energy mirror design, the reflective mirror surface, and the multifunctional substrate," according to Zhang, also the principal investigator for this STTR.

Brimrose Technology is working in collaboration with Penn State University's Applied Research Lab on the MDA award.

Washington, D.C. - Brimrose Technology Corporation is introducing a new generation of optical taggants which will again let the U.S. warfighter own the night and day in terms of being able to see and process critical information beyond what the human eye can see even with the help of 3rd generation night vision goggles. Optical taggants are target identifiers located on friendly or enemy personnel or material that enable the Warfighter to make critical decisions in target identification in a tactical environment. The announcement is being made here at the AUSA conference.

Brimrose is supplying its highly advanced SWIR AOTF (Short Wave Infrared Acousto-Optic Tunable Filter) hyperspectral imager to provide the Warfighter with "special eyes" to find and locate TTL (Tagging, Tracking & Locating) taggants which are not observable by commonly used 3G night vision goggles, which are globally available.

"The 21st century battlefield is evolving rapidly and for the U.S. Army to stay out in front of it we need to continue to employ tools and tactics that keep us ahead of those who would do harm to our nation" says Brimrose CEO Dr. Ron Rosemeier. "With these new taggants, we are opening opportunities at the edge that will make our fighting forces more effective."

The SWIR AOTF hyperspectral imagers let the soldier in the field identify optical taggants at a highly specific wavelength which is outside of the commonly viewed IR frequencies. When the taggant activates or fluoresces, the soldier can track friendly troop and material movements.

The soldier also has a Brimrose covert source invisible to the naked eye that he can track and locate which provides critical information about enemy troop and vehicle movement, weaponry, contraband, as well as being useful for other purposes. This source is also beyond the range of 3G night goggles.

It is critical that the optical taggants only be seen by the observing party, the U.S. Warfighter. When all parties have goggles that can see the activated taggants, as is the case with 3G IR goggles, they lose their effectiveness. The new generation of Brimrose taggants can be seen only by those using SWIR technology.

"The U.S. soldier must be in the position where he can make informed decisions" says Dr. Rosemeier. "U.S.-only readable optical taggants allow him to do that on a variety of fronts, including at the edge, where the gathering of enemy intelligence is critical."

The optical taggants themselves are made of a proprietary fiber material. Brimrose performs materials research with nano-materials and quantum dots, both of which are used to make the next generation of optical taggants.

The Brimrose hyperspectral imager and optical taggants will be demonstrated at the Brimrose booth (#1638) at the AUSA show Oct 21-23.

Leading Brimrose scientists and engineers are focused on providing ways to identify at a moment’s notice dangerous chemicals spread into the atmosphere in wartime and hazardous accident situations.

President and CEO Dr. Ronald Rosemeier, himself a physicist, has taken a personal interest in the work and is heading the effort. “The world we live in unfortunately is becoming an increasingly dangerous place,” said Dr. Rosemeier. "By instantly identifying poisonous chemical agents in the atmosphere we can potentially save countless lives."

Brimrose Technology Corporation has many years of experience in gas analysis using its proprietary acousto-optic tunable filter near infrared (AOTF-NIR) technology. The company is in the process of doing proof-of-principle testing using its AOTF multi-gas analyzer spectrometers.

Using the full spectral range, the spectrometers can potentially match samples of any gas with models already developed and deliver the results to waiting officials in a few seconds. Gas can be pumped into the flow cell of the gas analyzer continuously. The absorption spectrum of the sampled gas is then measured in real time in the full spectral range of the spectrometer, which can potentially be matched with models already developed. The results can be obtained and transmitted to a waiting official in a matter of seconds.

The proof of principle concept involves potentially mounting the AOTF-NIR spectrometer onto Brimrose’s autonomous unmanned flight vehicle, known as HERO (for Heli-Engagement Reconnaissance Observatory). HERO has the potential to fly in and through dangerous or hazardous areas and identify gases as it does so.

"Our warfighters and first responders are too valuable to be rushing in uninformed to dangerous chemicals in the air,” said Dr. Rosemeier. “We are moving rapidly to find a realistic solution to this problem."

Brimrose, a photonics and high-technology company, is launching an exciting new capability as the company has unveiled a series of reconfigurable, multipurpose unmanned aerial vehicles (UAVs) for potential tactical, surveillance and emergency applications.

With the advent of HERO (Heli Engagement Reconnaissance Observatory), Brimrose has the potential to collect a wide variety of data from the air using sensing and other data-gathering equipment.

"A core mission of Brimrose has been to help our clients better identify and characterize the environment and elements around them through our advanced acousto-optic technology and other products," said President and CEO Dr. Ronald Rosemeier. "By introducing controlled flight, HERO provides us with an entirely new dimension to use this sensing and data-gathering equipment extremely effectively."

The HERO series—which already has undergone preliminary testing--includes a variety of power, weight and multi-blade options, and provides real-time, 360 degree view capability that includes both CCD Color Video and Infrared (IR) Night Vision. The series also offers auto return-to-home base and point-to-point GPS navigation. The drone offers up to 30 minutes of flight time and up to 13 pounds (5.9 kg) of custom payload.

Some potential applications include active and passive target monitoring, crop monitoring, search and rescue, crowd control/monitoring, flood/fire disaster monitoring, and environmental monitoring.

Brimrose is a world technology leader in the area of acousto-optic components, NIR instrumentation, and advanced materials for space applications serving the U.S. government and worldwide commercial industry since 1979. For additional information, call 410-472-7070.


Acousto-Optic Tunable Filter-based (AOTF) Polarimetric Imaging System for Stand-Off Chemical Detection

The first award (CBD 13-104) is for an Acousto-Optic Tunable Filter-based (AOTF) Polarimetric Imaging System for Stand-Off Chemical Detection. Brimrose will apply its considerable understanding of AOTFs in the long-wavelength infrared (LWIR) region. The company intends to optimize the device fabrication techniques using mercurous halide materials.

The goal for Phase I of the research is to develop and design an AOTF spectral polarimetric imaging system that uses an LWIR focal plane array as the detector. In Phase II, the system will be fully built and demonstrated. The variety of potential applications include remote sensing, pollution detection, environmental monitoring and mapping, automobile emission monitoring, and process control in the manufacture of foods, beverages, semiconductors, petrochemicals and pharmaceuticals.

Development of Low-Cost Infrared Focal Plane Array for Passive Chemical Detection Using Colloidal Quantum Dots (CQDs)

The second award (CBD 13-105) is for Development of Low-Cost Infrared Focal Plane Array for Passive Chemical Detection Using Colloidal Quantum Dots (CQDs). This research is being done in collaboration with Research Triangle Institute in North Carolina.

The goal is to develop low-cost, long-wavelength infrared focal plane arrays (LWIR FPAs) using colloidal quantum dots of II-VI semi-metallic compounds. Brimrose intends to develop reliable fabrication processes to make mercury telluride (HgTe) CQDs, and methods to extend the capabilities into the LWIR range will be examined. The work is exploratory in that it has mainly occurred in the mid-IR range heretofore.

This research has the potential to replace far more expensive sensors that only operate effectively at cryogenic temperatures. Also, the techniques used to fabricate existing FPAs are very expensive and have low yields of usable sensors. The Brimrose research may lead to far less expensive sensors operating at room temperatures that potentially could be helpful to first responders, fire fighters, and military post-blast reconnaissance teams.
