摘要: 微光像增强器是微光夜视仪的核心器件，它是微光夜视整机性能和价格的决定因素。微光像增强器是在微弱的光线下工作的 ,因此必然是光能放大器。亮度增益是评价微光像增强器光电性能的一个重要参数，它直接影响了微光整机的性能，因此，对像增强器的亮度增益测试技术的研究具有重要意义。文中介绍了三代微光像增强器的亮度增益测量原理和装置，并对测量结果进行了不确定度评定。Abstract: The glimmer intensifier is core component of low light level night vision device, and it is the determining factor of glimmer night vision complete machine performance and price. Since the glimmer intensifier works under weak light , it is the light energy amplifier. Brightness gain is a key parameter of the glimmer intensifier electro-optic property assessment, which effects the complete machine performance directly, therefore, research on the brightness gain test technology of image intensifier has great significance. This paper introduced the principle and equipment of third generation glimmer intensifier brightness gain measurement, and carried on the uncertainty evaluation of the measurement result.
