Abstract: In the spaceborne infrared remote sensing system,the infrared detector is linked with the cryocooler,so that it can be cooled down to and kept at its working temperature.But,when using mechanical cryocooler,the effects of vibration and electromagnetic noises of the cooler on the detector is inevitable.To meet the requirement of the infrared detecting,these effects must be minimized.In this paper,the techniques for solving these problems,and for reducing heat leakage and improving efficiency of heat transfer are discussed.
