In pursuit of a low cost, high performance IR, Imager Litton Electro-Optical Systems has developed an Uncooled Lead Salt 320 X 240 camera. The 30 um pitch detectors consist of either Lead Sulfide or Lead Selenide photoconductors fabricated onto a CMOS Multiplexer Read-Out Integrated circuit. The multiplexer uses novel techniques to subtract the large bias current adaptively, and to integrate the residual signal current. The image is acquired in `snapshot' mode. A chopper provides a uniform reference. Although not necessary for functionality, a thermo-electric cooler is incorporated to improve performance. The signal is digitized off focal plane, and pixel substitution/correction functions are subsequently performed. The resulting video signal is either observed on a LCD display at the back of the camera or remoted to an external viewing device.
