Abstract
Chemical imaging sensors require focal plane arrays (FPAs) comprising long wavelength infrared (LWIR) detectors suitable for hyperspectral detection. These detectors require high sensitivity to account for the low photon counts in narrow wavelength bands. The required sensitivity elevates the associated costs, so a need exists for a lower cost LWIR FPA for use with chemical imaging sensors. The technical approach to providing this solution relies on EPIR's expertise in the molecular beam epitaxy (MBE) growth of HgCdTe on silicon substrates to reduce cost, improve yield and potentially improve performance. The potential performance enhancements include reducing the detector dark current through cost effective material improvements. Phase I of this program will focus on system trades including FPA geometry, spectral response, noise requirements and operating temperature that meet the system requirements while minimizing cost and risk, and maximizing yield. Outputs will include an FPA specifications document as well as single element infrared detector fabrication and characterization. Phase II will focus on infrared detector array manufacture and characterization, and will necessitate a partnership with a system house to integrate the FPA into an integrated detector dewar cryocooler assembly for testing. Phase III will focus on packaging and manufacturing scale-up to further lower costs.
