Summary
Description
Black Forest Engineering has identified innovative modifications in uncooled focal plane array (UFPA) architecture and processing that allows development of large format long wavelength infrared (8-14 ?m) imaging sensors to meet future NASA system requirements for a light weight, low power, and radiation tolerant imager. These modifications allow development of bolometer-based large format UFPA, with a pixel pitch of 20-?m and 1024x768 pixel elements with sensitivity comparable to commercially available UFPAs with 30-?m pixel pitch. The identified modifications are applicable to amorphous silicon bolometer-based UFPAs, such as those manufactured by Raytheon Commercial Infrared in Dallas, Texas.
