Photoelectric parameters testing system for CCD imaging electronics unit

According to the testing requirements for photoelectric parameters of CCD imaging electronics unit, as an important part in space optical cameras, the necessity for testing the photoelectric parameters of the CCD imaging electronics unit was introduced, the testing scheme was proposed, and the testing device was designed and developed. The device was debugged and calibrated, and a monochromator wavelength calibration coefficient of 1.003 29 was obtained. Moreover, the stability and the uniformity of the integrating sphere in radiation properties testing of CCD imaging electronics unit were conducted, and the results met the demands. Through the calibration for the detector by the standard detector, the relative spectral responsivity of the detector was got. The whole device met the testing requirements.
