摘　　要：分置式斯特林制冷机是红外探测器组件常用的制冷方式,具有冷量大,寿命长等特点。本文以耦合分置式斯特林制冷机的长波576×6碲镉汞红外探测器组件为例,进行了姿态翻转时的探测器组件均匀性变化试验,表征斯特林制冷机在不同翻转姿态情况下对探测器组件输出非均匀性的影响,并提出了优化耦合尺寸以及驱动控制器的方法。The split Stirling cooler is the common cooling way for the IRFPA, which has the characteristics of large cooling power and long l ife,etc. Taking LW 576 x6 MCT IRFPA as an example,the experiment of the uniformity variation is carried out when the posture of the detector is turning. The influence of the posture of split Stirling cooler on the uniformity is analyzed, and the coupling size and cooler controller are optimized.
