To reduce the cost of new hardware development, the Missile Defense Agency (MDA) is developing fast new computational tools that enable in-the-loop hardware testing. The MDA and contractors have developed high-fidelity scene modeling tools such as the Fast Line-of-sight Imagery for Target and Exhaust-plume Signatures (FLITES) to test optical signature trackers. Currently, these high-speed tools ar ...

Active defects negatively impact the performance of IRFPAs by increasing noise at various levels up to, and including, catastrophic degradation. Evidence indicates that"killer defects"are related to the interaction of open core screw dislocations with impurities that remain after substrate preparation, prior to HgCdTe growth. This impurity diffusion creates a conducting channel that shorts the j ...

For HgCdTe infrared focal plane arrays fabricated on Si substrates, a model has recently been proposed to account for the disparity between the density of failed pixels and the density of dislocations that are present in the HgCdTe junction region. The model distinguishes between active and inactive dislocations and offers a hypothesis that dislocations are active only when they intersect particul ...

Silicon wafers oriented on (112) are the preferred substrates for deposition of mercury cadmium telluride layers by molecular beam epitaxy. Surface defects introduced during polishing of the wafers degrade the quality of the epitaxy and the performance of infrared detectors fabricated within these materials. We propose a process for reducing the density of the defects that are inherent in the si ...

Applied Technology Associates (ATA) proposes the development of the stable platform for a new Optical Inertial Reference Unit (OIRU) titled the Space Qualified MSTAR Inertial Reference Unit (MIRU-SQ). The components and functions of an OIRU can be easily split between the stable platform and electronics subsystem. Because of the expensive nature of space qualified design, purchasing, and testing ...

In the proposed effort, SK Infrared LLC (SKI), a spin-off from the Krishna INfrared Detector (KIND) laboratory at the University of New Mexico (www.chtm.unm.edu/kind), in collaboration with Raytheon Vision Systems (RVS) and Intelligent Epitaxy Inc (Intelliepi) is proposing a systematic study with the following two objectives. (a) Optimization of the epitaxial growth parameters to reduce dark cur ...

In the proposed effort, SK Infrared LLC, a spin-off from the Krishna INfrared Detector (KIND) laboratory at the University of New Mexico (www.chtm.unm.edu/kind), in collaboration with Raytheon Vision Systems (RVS) is proposing to develop a dual band based imager using a novel unipolar heterostructure design with Type II InAs/GaSb strained layer superlattice detectors. The dual bands that are chose ...

Applied Technology Associates (ATA) proposes the development of the electronics subsystem for a new Optical Inertial Reference Unit (OIRU) titled the Space Qualified MSTAR Inertial Reference Unit (MIRU-SQ). The components and functions of an OIRU can be easily split between the stable platform and electronics subsystem. Because of the expensive nature of space qualified design, purchasing, and t ...

Through this research effort, DSR is developing test equipment that can be used by the Air Force to investigate inert and live explosive material properties through a variety of different pressure and temperature environments. Strain-rate levels are adjustable and will vary between 10-5-10-2 s-1 depending upon the stiffness and strength of the test material. 25.4-mm-diameter specimens with lengt ...
