Fuels for Army use undergo rigorous analysis to determine many chemical and physical properties before they are used in Army vehicles. The property of fuels to produce smoke or soot is one such specification used to determine fuel quality. Smoke production of a diffusion flame produced by a kerosene fuel can be correlated to the chemical composition of the fuel. Unfortunately, the standard used to ...

This proposed project is concerned with the design, fabrication, and demonstration of a new class of plasmonic nanostructures for single molecule surface-enhanced Raman spectroscopy for biological and chemical sensing applications. A complete design of the plasmonic nanostructures with large local field enhancements (E/E0>100) will be formulated, and the fabrication procedures will be developed fo ...

Leveraging Agiltron"s industrial leading developments and production of Raman instruments, external cavity laser and nonlinear optical components, we propose to develop a new class of high performance compact deep ultraviolet (UV) laser for Raman spectroscopy. The approach is closely coupled with recent progress in GaN blue laser and external resonator enhanced second harmonic generation (SHG) to ...

Bridger Photonics and the University of Arizona will develop a passive multi-band compressive sensor for imaging and object recognition applications. The Army has identified a need for multi-band imagery for intelligence, surveillance and reconnaissance missions among others. Multi-band systems offer enhanced discrimination capability and the ability to perform in adverse conditions (at night, smo ...

Detecting light at the single photon level is a fundamental measurement function that is useful in a wide variety of applications, including such diverse fields as biological spectroscopy, laser ranging, and quantum communications. Avalanche photodiode (APD) based single photon detectors (SPDs) are very convenient in that they are small solid state devices that don"t require cryogenic cooling. Si- ...

In the past few years, there have been promising demonstrations of new approaches to short-gate (i.e., sub-nanosecond) operation of single-photon avalanche diodes (SPADs) with gating frequencies as high as 2 GHz. However, these demonstrations have had limitations, including operation at just a single fixed frequency, fairly high residual afterpulsing levels, and the lack of industrialization req ...

Very compact, robust, and low cost multi wavelengths burst lasers for standoff CBRNE (Chemical, Biological, Radiological, Nuclear, and Explosive) detection and identification are proposed. Although a single focused laser pulse on target can do the detection, the probability of hitting the right contaminated spot is low. Therefore, scanning a laser pulse train will cover a larger suspected contamin ...

Q-Peak Inc., in collaboration with The Johns Hopkins University (JHU), proposes to develop an extremely compact, air-cooled, lightweight, multi-wavelength, burst-mode laser based on the combination of a Q-switched, Nd-doped, oscillator-amplifier laser, and efficient, robust nonlinear optical frequency converters.

This proposal is to develop a High Risk Rapid Ethnographic Assessment Tool (HRREAT) that will provide commanders and their staff with a fully-integrated, user-friendly suite of tools for the rapid collection, management, analysis, modeling, and visualization of ethnographic data in denied areas to enhance planning and decision making activities. Ethnographic data has become highly important in ...

Obtaining support from the local population is crucial for successful counterinsurgency (COIN) operations. US forces often fail to adequately understand the ethnographic characteristics of foreign populationswarfighters need access to ethnographic methods which help them to rapidly capture and interpret cultural, social, and economic data. A warfighter in high-risk areas needs easy-to-use tools th ...
