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. For more information about Brimrose employee training, please click on our customer service webpage and for photos of Brimrose training exercises, click here.

“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 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.”

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.

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.
