Design of Imaging Circuit for 128×128 Two-color Infrared Detector Arrays
128×128元双色红外探测器成像电路设计

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 animaging infrared guidance system.
