Paper Abstract

DRS has developed and demonstrated a family of miniaturized, low-power uncooled infrared focal plane camera products integrated with our 1-mil pixel size 640 x 480 and 320 x 240 uncooled infrared focal plane arrays (UIRFPA). The UIRFPA cameras operate from -40°C to +55°C without UIRFPA temperature regulation using our patented TCOMP sensor concept. Furthermore, they are software based, with significant memory and signal processing overcapacity, which supports significant camera setup reconfigurations without having to undergo camera firmware and hardware modifications. The elimination of the UIRFPA temperature regulation requirement results in reduced sensor power and prompt sensor turn-on. The new 320 x 240 camera weighs less than a quarter pound (including batteries and a 23 mm aperture F/1.2 optic), and dissipates approximately one watt when operated at a full 60 Hz frame rate. The 640 x 480 camera dissipates about two watts when operated at a TV compatible 30 Hz frame rate. This paper describes the UIRFPA camera products, their features and capabilities, and their key performance characteristics. Illustrative examples of thermal image quality are also included.
