针对多角度偏振成像仪探测器光电性能的评估需求,研制一套图像传感器光电性能参数通用测试系统,并提出一种基于珀耳帖效应的热电制冷器和低温循环机相组合的探测器控温方法。实验结果表明积分球的光源稳定性为0.036%,照度均匀度≥99.3%,探测器制冷系统降温速率约为2.2 ℃/min,温控精度优于±0.15 ℃,实现在-10~25 ℃的工作温度范围内对量子效率、光响应不一致性、暗电流、满阱电荷和光响应非线性等关键性能参数的测量,多角度偏振成像仪探测器不同波长下的光响应不一致性优于3%,光响应非线性优于1%,工作温度升高至9 ℃暗电流增加1.25倍,近红外波段的量子效率变化3.58个百分点。探测器性能的评估为多角度偏振成像仪整机的性能测试和定标需求提供保障。
Abstract
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.
