The goal of the proposed work is to develop simulation and analysis model based on cognitive task analysis for cyber situation awareness, for human-in-the-loop testing and training. Cognitive task analysis technique is a prominent approach that captures knowledge representation used by experts to perform complex tasks. It provides a comprehensive vulnerability assessment using cognitive metrics t ...

Military applications, such as IRCM (Infrared Countermeasures) and stand-off sensing, require highly efficient optical sources with power outputs for room temperature continuous wave operation of several to a hundred watts in the 3-5 micron and 8-12 micron spectral bands. While quantum cascade lasers (QCLs) have become the sources of choice in these spectral regions, the only realistic option to ...

Many military applications require efficient optical sources producing several to hundred watts in continuous-wave (CW) or quasi-continuous-wave (QCW) operation at room temperature (RT) in the MWIR (3-5 micron) and LWIR (8-12 micron) regions. While QCLs have become the sources of choice in these spectral regions, the only realistic option to attain hundred-watt power level with good beam quality i ...

Vescent Photonics proposes to develop a compact laser system and integrate it with a cold-atom micro primary standard developed under the DARPA IMPACT program. In phase I we will investigate performance enhancements resulting from immobilizing the cold-atom sample with an optical lattice formed from an optical field whose wavelength is chosen to minimize the differential light shifts between the s ...

To solve the DARPA need for high-performance MEMS-based optomechanical accelerometers, Applied Optronics proposes to develop a Compact Integrated Silicon Nitride Microresonator Accelerometer (OPTIMA), which is based on a combination of a high-Q silicon ni

ABSTRACT: There has been a growing interest and increased R & D activities in applying THz technology to biomedical, security, communications and science/manufacturing imaging, etc. However, even with all these research activities, there are very limited choices of test and measurement instruments in the THz range. Despite wide availability of RF/microwave (below THz) and optical (above THz) netw ...

As strontium and other alkaline-earth metals become increasingly attractive for ultracold-atom applications, there is a growing need to develop compact, robust systems for cooling, trapping, and studying these elements. In this proposal, ColdQuanta will team with Dr. Jun Ye at JILA and the University of Colorado at Boulder to develop a portable, turn-key system that can produce, utilize, and optic ...

Current of the shelf commercial laser systems that are used for LIBS and other optical detection techniques are too costly, large, low performance and unreliable. The reason for it is because commercial laser systems are designed for continuous operation. Only one or few laser pulses are needed for detection, therefore, low cost burst lasers with the proper parameters are needed. Burst mode operat ...

We intend to use the emerging technology of compressed sensing and related new algorithms of information science to (1)increase our capacity for hyperspectral image acquisition beyond current capacity by developing new imaging and spectroscopic systems,(2) expand the frontiers from signal recovery to new applications, emphasizing knowledge learning including target and anamoly detection, and (3)st ...
