制冷机与红外探测器冷链耦合技术研究

摘要

Cryocoolers provide low working temperature for infrared detectors,because infrared detectors need a low temperature environment for imaging.There are multi-coupling modes between cryocoolers and infrared detectors,but the cold chain linking technology is mainly introduced in paper,and research progress of this technology is summarized and discussed.At last,its application prospect is forecasted.%红外探测器在航天应用中通常在低温环境下才能成像,因此需要耦合制冷机为其提供稳定的低温工作环境,满足它的工作需求.制冷机与红外探测器耦合采取的方式有多种,本文主要介绍冷链技术的耦合方式,综合分析国内外多家单位的试验情况,对冷链耦合的应用前景进行了分析说明.
