Abstract

A new method for tracing rays through graded-index media is presented. The method essentially consists of transforming the ray equation into a convenient form and solving the resulting equation using a standard numerical technique. A detailed comparison of this method with existing methods has also been made, and it is shown that for obtaining a desired accuracy this method requires much less computational effort.

摘要

提出了一种用于追踪光线通过渐变折射率介质的新方法。该方法主要包括将光线方程转化为一种方便的形式，并使用标准数值技术求解所得方程。还对该方法与现有方法进行了详细比较，结果表明，为获得所需精度，该方法所需的计算量要少得多。
