实验室条件下微光环境模拟

Simulation of Low-light-level Condition in Laboratory

从光谱和光度两个方面分析了微光夜视系统的实际工作环境,设计了照度连续可调的 微光光源,利用稳流电源供电,实现了实验室条件下的夜天光模拟。经标定,该微光光源的不 均匀性小于1％。

The actual working condition of night visions is analyzed from aspects of spectrum, illuminance low-llght- level （LLL） source with continuously adjusted illuminance is designed,and the simulation of LLL condition in lab is realized by using electrical source of steady current. The unhomogenity of LLL source is below 1%.
