The split Stirling cooler is the common cooling way for the IRFPA,which has the characteristics of large cooling power and long life,etc.Taking LW 576×6 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.
