以下后
暗电流噪声成为电子倍增CCD相机的主要噪声源。由于制冷可以显著降低电子倍增CCD的暗电流噪声
因而其成为影响电子倍增CCD相机成像质量的重要因素。本文在分析比较不同制冷系统优缺点的基础上
提出了适用于航天应用的电子倍增CCD相机制冷系统。通过构建电子倍增CCD相机的噪声模型
分析了不同制冷效果对电子倍增CCD相机成像质量的影响。分析结果表明
电子倍增CCD相机焦面的温度从30℃降低到-30℃

the dark current noise becomes a primary noise source of the EMCCD camera. As the cooling can reduce the dark current noise of EMCCD camera remarkably
it has been one of the important factors influencing imaging quality of EMCCD camera. This paper analyzes and compares advantages and disadvantages of different cooling systems in the EMCCD camera
then it proposes a new cooling system for the EMCCD camera which is fitful for space-borne applications. By establishing a noise model of EMCCD camera
the influences of different cooling effects on imaging quality of EMCCD camera were analyzed. Analysis results indicate that Signal to Noise Ratio(SNR) of EMCCD camera is improved from 82.9 to 87.2 as the temperature of focal plane is lowered from 30℃ to-40℃. In addition
imaging quality of EMCCD camera can be improved effectively. The research results provides design references for development of EMCCD cameras used in space sciences.shen.
