Abstract

Cryogenic technology has been developed cooperatively with infrared detection technology, which is of great significance for the development of space science and technology. To illustrate this coordinated development, the relationships between the infrared wavelength and the dark current in detectors with cryogenic temperature are analyzed, which shows the importance of cryogenic technology for infrared detection. Based on an analysis of infrared detection characteristics and cryogenic temperature requirements in different temperature zones, the development direction of cryogenic technology for infrared detection in space is analyzed and combined with the application of cryogenic technology in several key infrared space missions.

摘要

低温技术是与红外探测技术协同发展起来的，这对空间科学技术的发展具有重要意义。为说明这种协同发展，分析了低温温度下探测器中红外波长与暗电流之间的关系，这表明了低温技术对红外探测的重要性。基于对不同温度区域红外探测特性和低温温度要求的分析，结合低温技术在几个关键红外空间任务中的应用，分析了空间红外探测低温技术的发展方向。
