HgCdTe红外探测器信号抑漂与一致性研究

摘要

Aiming at the problem of signal floating and non-consistency of the three-stage thermoelectrically cooled photoconductive (PC)HgCdTe Infrared detectors,the causes are analyzed and studied.The necessity of output consis-tency and signal stabilization is pointed out.This paper focuses on the influence of adjusting the bias current on the output voltage.It is used the zero-calibration technology,the signal synthesis and the restoring technology to eliminate and control the voltage floating .%对三级半导体制冷HgCdTe红外探测器信号输出不一致性和信号漂移产生原因进行深入分析与研究，并说明使其输出一致与信号稳定的必要性，着重论证了调整偏置电流对探测器输出的影响，并采用校零技术，信号合成与还原技术等对抑制漂移的基本方法。
