在空间红外遥感中，红外探测器是通过与制冷机的耦合获取冷量的。着重讨论为满足红外探测的需要，如何最大限度地消除空间的振动、电磁干扰等不利因素的影响。同时介绍降低漏热，提高冷量传输效率，从而保证制冷机与红外探测器良好耦合的技术。 In space infrared remote sensing, the infrared detector obtains the cooling capacity through the coupling with the refrigerator. Focus on discussing to meet the needs of infrared detection, how to minimize the impact of space vibration, electromagnetic interference and other unfavorable factors. At the same time introduced to reduce leakage and improve the cooling capacity of the transmission efficiency, so as to ensure the refrigerator and infrared detectors good coupling technology.
