摘　　要：文中就斯特林制冷机应用在三光窗杜瓦红外探测器组件中对红外探测器的信号产生的干扰问题进行了多方面探讨、测试及分析研究。从制冷机驱动电源入手 ,研制出了一种低干扰制冷机驱动电源 ,并对整个系统的安装调试进行了抗干扰设计 ,有效地控制了系统对探测器芯片信号产生的干扰 。In this paper, we tested and analyzed the interferences produced by stirling cryocooler which is used in IR detector composite with three optical windows dewar. We developed a new low interference cryocooler driven power supply and completed some anti-interference design for installation and regulation of whole system. The interference or the detector chip signals produced by the system was effectively curbed. So the requirements of customers can be satisfied.
