摘要
常见微光瞄准镜的分划机构形式有3种,即置于光阴极面上的暗分划机构,置于屏面上的暗分划机构以及亮分划投影机构。本文通过理论分析,给出了3种分划机构分划精度绝对误差和相对误差的应用公式,并对提高分划精度的途径进行了探讨,着重介绍了消除亮分划投影机构分划误差的方法。
There are three types of reticle systems commonly used in the Low Light Level Sight, i.e. dark reticle on photocathode, dark reticle on fluorescent screen and bright projected reticle. Based on theoretical analysis, useful formula were obtained for analyzing the absolute and relative errors of the three reticle systems. The methods to increase the reticle accuracy, especially for the bright projected reticle, are also discussed.
