Tracing rays through graded-index media: a new method.

A Sharma1, D V Kumar, A K Ghatak.   

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.
