Abstract

A microprocessor based compensation electronics system has been developed in conjunction with a video image display for 64 x 64 (Hg,Cd)Te hybrid staring arrays. The system has a data throughput rate of 5 MHz, where offset (12 bits resolution), gain (8 bits), and defective cell corrections take place in real-time. While imaging in real-time, the system also compiles quantitative data on the array performance such as responsivity and noise in a separately allocated memory. A general purpose computer can be interfaced to this systen to extract array data and perform statistical computations. The system can readily be expanded for staring arrays of 256 x 256 elements without major modifications.
