Research Institution
Longwave infrared (LWIR, 8-12µm) focal plane arrays (FPAs) play an important role in hyperspectral chemical and biological (CB) sensing and spectral imaging. Existing thermal detectors are unable to meet the high sensitivity and fast response requirements of many hyperspectral chemical and biological sensing applications. FPAs based on photon excited electron generation process can fulfill the speed and sensitivity requirements. However, they show high noise, and thus need to be cooled down to<80 K to reduce the noise. The requirement for cryogenic cooling systems adds cost, power consumption and reliability issues, thereby making it unsuitable for standoff sensing and detections. In SBIR phase I research, we have developed a new low noise LWIR photodetector, demonstrated large photoresonsivity, high photodetectivity and its chemical sensing and imaging capability. Motivated by the Phase I feasibility and advantages demonstration, In Phase II, we will optimize the LWIR photodetector and FPA technology specifically for long distance standoff CB molecule and aerosol detection and spectral sensing and mapping. A prototype of the LWIR FPA will be developed and packaged with integrated detector dewar cryocooler assembly (IDDCA) and assess interface compatibility with Edgewood Chemical Biological Center (ECBC)'s existing CB molecule and aerosol spectral sensing system.
