摘　　要：为了获得微光像增强器综合性能测试中光源输出不同光照度,对传统的光源结构以及存在的局限性进行了分析。根据综合性能测试中对光源照度的不同要求,借助积分球对光线的漫反射作用和微度计控制光栏改变光输入量的连续性,解决了光源输出光照度大范围连续调变功能的问题,对改进后的光源照度输出范围及均匀性进行了测量,得到该光源的出射光照度为2.5×1-0 5lx^680 lx,出射光均匀度为2.3%,该方法适用于像增强器的各种性能参数测试。In order to obtain the different output illuminance of the light source used for lowlight-level image intensifier comprehensive testing, the traditional light source structure and its limitation were analyzed. According to the different illuminance needed in comprehensive testing, the large-scale continuous illuminance-adjusting function of light source was studied by analyzing and improving the traditional light source, based on the diffuse reflection characteristic of the integrating sphere and the continual characteristic of the micrometer. The output characteristic of the light source was specifically analyzed. The output illuminance of 2.5 × 10^-5 1x～680 1x and the output light uniformity of 2.3% were achieved by testing in an experiment. It shows that the light source has a large illuminance range and higher output uniformity. Therefore, it can be used in testing the image intensifiers.
