Uncertainties evaluations in the ray-tracing algorithm based on Monte Carlo method

摘要

Although Ray tracing method is an effective aided design method in optical system, the uncertainty caused by this method is not very clearly. The relationship between the number of rays and uncertainty has been explored in this paper, while using the Monte Carlo algorithm in Ray tracing method. It shows that if the simulation relative deviation should be limited to 0.1%, at least 1000000 rays must be used.
