摘要
本文根据微光夜视仪分辨率经改进了的通用公式,通过对系统中诸参数内在联系的分析,找出一种根据目标在夜天光条件下(景物有不同的对比度和亮度),利用“人工眼”(由微光物镜和像增强器组成)的结构参数,求解系统中心分辨角(mrad)的新计算方法,作为视距估算的基础,同时对诸参数在其总体性能贡献方面作了初步的分析。列举国外某公司系列产品为例,计算结果表明,理论计算数据与实验结果基本上是吻合的,新的计算公式是切实可行的,具有一定的参考价值。
From the general formula of resolution of low light night vision instrument,in this paper, a new calculate method of central resolving angle of system can be derived with analysing internal relations of several parameters and using structural paramaters of 'artificial eyes'. The new calculate method can be used for estimating the distance of vision. Then the related parameters and their influences on the total performance of system were analysed. By calculating some products of foreign companies, the theoretical results approximatly coincide with the experimental results. The new formula proves to be really effective, and is of reference value.
