摘要
介绍了针对128×128元双色碲镉汞红外焦平面探测器而设计的一种探测成像系统。该探测成像系统包括探测器适配、视频模拟信号调理、模数转换、非均匀校正以及数字图像输出模块等功能模块。结合光学系统和上位机图像记录软件,对该探测成像系统进行了相关成像试验及性能测试。目前,该探测成像系统已成功应用于红外导引系统。
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.
