This overall objective of this research task was to develop an alternative material system for use in VLWIR FPAs with the sensitivity required at 40K for long range sensing and discrimination of cold, dim targets. The alternative material system under development is based on thin alternating layers of indium arsenide and indium gallium antimonide creating a superlattice material capable of infrared detection out to 30 microns. A VLWIR detector adds detection range and discrimination to a space based platform. Operation at 40K provides significant reduction in size, weight and power for this application.
