The spectral matching factors between photocathode spectral response and scene reflecting spectrum were calculated for the LLL night vision system with laser illuminator.
根据夜间景物的反射特性以及激光辐射光谱特性,求出了在激光助视下,夜间暗绿色涂层、粗糙混凝土和绿色草木的反射光谱,计算了所研制的头盔式激光助视/微光夜视仪光电阴极光谱响应与景物反射光谱之间的匹配系数,分析了其对照度、对比度等参数的影响,对野外条件下的夜视仪的视距估算和性能仿真可起到指导作用。
