In response to the demand for the photoelectric performance evaluation of multi-angle polarization imaging detectors, a universal testing system for photoelectric performance parameters of image sensors is developed herein, and a Peltier effect-based thermoelectric cooler and low-temperature cycler are combined to control the temperature of the detector. Experimental results show that the light source stability of the integrating sphere is 0.036%, the uniformity of illuminance is ≥99.3%, the cooling rate of the detector refrigeration system is approximately 2.2 ℃/min, and the temperature control accuracy is better than ±0.15 ℃, and the temperature is -10--25 ℃. For the measurement of key performance parameters such as quantum efficiency, photo response non-uniformity, dark current, full-well charge, and optical response nonlinearity within the operating temperature range, the photo response non-uniformity of the multi-angle polarization imaging detector at different wavelengths is better than 3%, The optical response nonlinearity is better than 1%, the dark current increases by 1.25 times when the operating temperature from 0 ℃ to 9 ℃, and the quantum efficiency in the near-infrared band changes by 3.58 percentage. The performance evaluation of the detector guarantees the test performance and calibration requirements of the multi-angle polarization imaging detector.
