摘要	CCD mosaic technology can effectively increase space camera's field of view and image width. CCD's performance difference will decrease space camera's image quality. In order to screen the same high-performance CCDs for wide field of view space camera, a method of CCD test and screening was proposed. Firstly, the design of CCD' s imaging circuit and the test method of CCD' s spectral and radiant characteristics were introduced. Then, the screening process of the CCD was introduced, the first step was screening CCD on the basis of the geometry characteristics, signal-to-noise ratio, relative spectral responsivity, photo response non-uniformity, non-uniformity, non-linearity, dark current, and dynamic range, then the poor-performance CCD would be removed. Secondly, the CCD on basis of radiant response consistency was screened. And data analysis shows consistency screening method of saturation irradiance is better than consistency screening method of responsivity. Finally, the most consistent four CCDs was screened from ten CCDs by consistency screening method of saturation irradiance, whose saturation irradiances' relative deviation was 0.23%. The screened four CCDs has been used in a wide field of view space camera, which received wonderful results.
