摘要
从光电器件对光源的响应率出发,引伸出光电阴极与景物之间的光谱匹配系数表达式,计算了S25光电阴极与暗绿色涂层和绿色草木的光谱匹配系数。S251光电阴极在满月光下,对暗绿色涂层的光谱匹配系数为0.5512,对绿色草木为0.2783;在晴朗星光下,则分别为0.2662和0.1255;对S252光电阴极,前者分别为0.7174和0.6820,后者分别为0.5741和0.4840。计算结果对夜视系统视距估算的修正有较高的参考价值。
According to the responsivity of photoelectric device for a light source, the formula of spectral matching factor of photocathode for object is deduced. The spectral matching factors of S 25 photocathodes for dark green paint and green vegetation are calculated and compared. To S 251 , the spectral matching factors for dark green paint and green vegetation are 0.5512 and 0.2783 under the full moon radiation. They are 0.2662 and 0.1255 under the clear star radiation. To S 252 , the former are 0.7174 and 0.6820 and the latter are 0.5741 and 0.4840. It is referential to evaluate visual range of night vision system through analyzing the results.
