Abstract
A detection imaging system for 128×128 two-color HgCdTe infrared focal plane arrays is designed. The system consists of a detector adapter module, a video analog signal conditioning module, an analog-to-digital converter module, a non-uniformity correction module and a digital image output module, etc. The imaging features and performance of the system are tested together with the optical system and the host computer image recording software. So far, the detection imaging system has been successfully used in an imaging infrared guidance system.
