在军事上应用的高灵敏度红外探测器,大多数需要在低温下才能工作。红外探测器的密封设计也随着整机的技术性能和选择的冷却方法而变化。本文将介绍红外探测器与低温的密切关系。一、致冷原理为适应红外探测器在不同场合下的应用而采用了多种致冷方法。研制成功了各种致冷器 Most of the highly sensitive infrared detectors used in military applications require low temperature operation. Infrared detector seal design also varies with the technical performance of the machine and the cooling method of choice. This article describes the close relationship between infrared detectors and low temperatures. First, the cooling principle In order to adapt to the application of infrared detectors in different occasions and adopted a variety of refrigeration methods. Developed a variety of refrigerator
