Abstract

The design, development, and characterization of a new, low-power, wide operating temperature range miniature short wave infrared (SWIR) camera for military applications is described in this paper. Such applications typically require operation over an extended(<-35C to >65C) temperature range. The camera technology is based on standard indium-gallium-arsenide (InGaAs) focal plane array (FPA) technology, but eliminates the thermal electric cooler (TEC) to both expand the operating temperature range and minimize power consumption. To compensate for variable FPA temperature, new algorithms were conceived and implemented in real time camera hardware resulting in a camera with an operating temperature range wider than that possible by stabilizing with a single stage peltier cooler. The additional benefit is reduced power consumption at temperature extremes and concomitant reduction in required thermal management. Imagery and results will be presented from 320x256 and 640x512 arrays.
