Abstract
Conventional ray tracing cannot always adequately model propagation of optical beams. We compare three approaches for modeling diffraction effects throughout an optical system: (1) FFT-based, (2) Gaussian beam decomposition, and (3) the SAFE method of Forbes and Alonso. The basic idea behind each method is described and some simple examples are given that highlight the main features of each method.
