摘　　要：红外整机成像时需要对红外探测器的输出进行非均匀校正,来获得相对均匀可观的图像。在一款碲镉汞长波红外探测器整机成像实验时,图像出现了“暗环”现象,通过分析确认了“暗环”现象的机理,并通过优化改进,消除了成像“暗环”,为其他长波红外探测器成像应用提供了借鉴。Infrared imaging requires non-uniform correction of the output of the infrared detector to obtain a relatively uniform and impressive image.The dark ring phenomenon occurs during the imaging process of long-wave infrared HgCdTe detector systems,and the mechanism is confirmed through analysis,and the imaging dark ring is eliminated through optimization and improvement.This method serves as a valuable reference for other applications utilizing long-wave infrared detectors in imaging.
