摘　　要：针对光学准直系统中用作反射镜的直角棱镜的特点,使用三维空间解析几何方法,对入射光线与反射光线的空间位置进行分析,推导出了直角棱镜的棱线水平度(或铅垂度)对斜瞄时测量结果影响的计算公式,并进行了实验验证。The utilization of right angle prisms as reflecting mirrors in optical aiming system is considered. The relation between incident light and reflected light is calculated by analytical geometry method of three dimensions. The expressions of the effect in measuring are derived when the ridge is oblique, and the related experiment is demonstrated.
