Abstract

The GUERAP III is a sophisticated stray light analysis computer program. It uses the Monte Carlo method with importance sampling to trace random real rays through an optical sensor model. The program is useful for calculating stray light in an existing optical sensor and for determining dominant paths of scattered light to aid in the improvement of an optical baffle. The accuracy of the program depends on the accuracy of the input data for geometry and surface scatter characteristics. The uncertainty in the random ray trace depends on the proper use of importance sampling.
