Abstract

An algorithmic solution to the general problem of a light ray entering a cylindrical lens, undergoing refraction at two surfaces, and then exiting, is developed. The algorithm is used to predict projection patterns and other characteristics of a laser beam passing through a tilted cylindrical lens and being projected onto a flat screen. An interactive software program with graphing capabilities that allows a user to experiment with the model is presented.
