摘要

为将低等级探测器应用于宇航等高可靠性应用环境，对探测器进行可靠性环境试验考核至关重要。本文提出了一种探测器的热真空实验方法，对多种型号星载探测器进行热真空环境考核试验，通过对比热真空环境试验前后探测器的相对光谱响应率、暗电流、制冷器驱动电流、探测器制冷特性等参数的变化，分析各型号探测器热真空环境的适应性，从而在早期暴露可能存在质量及其他缺陷的产品，筛选出性能最优产品用于宇航产品。试验结果表明，参试的探测器在热真空环境试验考核和筛选之后的各项性能指标满足设计要求，具有很好的可靠性，可以满足航天载荷应用需求。

Abstract

To apply low-level detectors in high-reliability application environments, such as those in the aerospace field, it is important to test the environmental reliability of such detectors. In this paper, a thermal vacuum experiment method is proposed to test various types of space-borne detectors. By comparing the changes in the relative spectral response rate, dark current, driving current of the refrigerator, and refrigeration characteristics of each type of detector before and after the thermal vacuum environment test, their adaptabilities in the thermal vacuum environment are analyzed to enable early popularization. To avoid products with possible quality and other defects, only those products demonstrating the best performances are selected for aerospace applications. The results show that based on the performance indices of detectors that meet the design requirements after the thermal vacuum environment testing and screening, such devices have good reliability and stability, which can meet the requirements of aerospace loads.
