摘要
斯特林制冷机的电磁兼容性问题是导致红外凝视相机探测性能下降的一个重要原因。对斯特林制冷机的电磁干扰进行研究,在此基础上进行了电磁兼容性设计,减小了电磁辐射干扰,提高了凝视相机的探测性能,对于红外探测器意义重大。通过制冷机改进之后的图像信噪比验证了设计的成功。
EMC problem of Stifling cooler is an important reason for the decline of detective performance of IR staring cameras. The electromagnetic interference of Stifling cooler was studied in this paper; The EMC design based on this work reduces the electromagnetic interference and improves the detective performance of IR staring cameras. The design was verifieti through the SNR of the images.
