摘　　要：为了提高批量微光像增强器性能参数的测试速度,通常采信单次测试数据作为测量结果。在该情况下,参数单次测量结果的误差将直接决定性能评价结果的准确性。以微光像增强器积分灵敏度的参数测试为例开展单次测量误差评定,通过对微光像增强器积分灵敏度的测试方法、测量装置、数据计算等误差情况进行综合分析,计算得到的积分灵敏度单次测量最大误差为6.7%;在该基础上,提出了采用更高加工精度光阑、对入射光测量位置进行修正以及阶段性辅助参量重复性测量校对的积分灵敏度单次测量误差控制方案。研究结果对微光像增强器批量化快速测试具有重要的指导意义和参考价值。In order to improve the test speed of performance parameter for lot size of low-level-light(LLL)image intensifiers,the single test data is usually used as the measurement result.In this case,the error of parameter single test result will directly determine the accuracy of the performance evaluation result.The parameter test of integral sensitivity for LLL image intensifiers was taken as an example to evaluate the single test error.Based on the comprehensive analysis of the errors of test method,measuring device,data calculation and so on for the integral sensitivity of LLL image intensifiers,the single test maximum error of integral sensitivity was calculated to 6.7%.On this basis,the single test error control scheme of integral sensitivity using a diaphragm with higher processing accuracy,corrected incident illuminance measurement position,and stage auxiliary parameter repeatability measurement calibration was proposed.The research results have important guiding significance and reference value for the rapid test of lot size of LLL image intensifiers.
