摘　　要：锥体棱镜是一种重要的逆向反射器 ,它广泛应用于远距离测距等方面。同时也是一种精度高、加工难度大的光学元件。介绍了锥体棱镜的两种加工工艺及其特点 ;着重叙述了立方体切角的方法 ,即借助于 T型抛光定位夹具和切角定位夹具加工锥体棱镜的工艺过程。同时给出了当用干涉法测量锥体棱镜时 ,干涉图的判别原则和棱镜合格时干涉图的特点。该方法对综合角度误差≤ 3″的锥体棱镜来说可获得很高的合格率。Corner cube prism is an important counter rejector which is widely applied in range measurement and is also an optical elemet with high accuracy and difficult to process In this paper, two processing technologies and characters of corner cube prism are simply described Cube cutaway method with the aid of T polished positioning fixture and to process corner cube prism is mainly discussed By measurement with interferometry the judging principle and the characters of interference patterns of qualified cube prism have been showed
