摘要
本文解决了在光学软件中对各种复杂棱镜进行实际光路追迹的问题,给出了对其中各种偏心、倾斜工作面通用的坐标变换公式,并着重介绍了对屋脊棱镜、角反射镜等具有特殊几何光路的棱镜的光路计算方法。
In the design and analysis of optical systems folded by prieme, the conventional method of unfolding the prisms and treating them as glass slabs has its limitations. In many cases (such as in the toleranoing of prism angular errors), surfaoe-by-surface finite ray-traoing is needed. Coordinate transfer formulae required in tracing rays through deoentred and tilted surfaces are derived in a general and simple form. A new method is developed for ray-tracing through roof prisms and corner cube prismswhich have special geometric structures.
