Abstract: The invention relates to a method for computationally determining optical properties of a channel waveguide, according to which, for an incident ray entering an entrance surface, the distribution of intensity over an emergence surface is determined by adjoined partial rays that possibly split up. From an incident partial ray striking the outer surface, a predetermined algorithm determines a reflected main ray and, in so far as it is necessary according to the ensuing course of events, determines a number of scattered rays of a higher order, which depict partial rays and are recursively traced further. Each partial ray is either a primary ray or a secondary ray. When the incident partial ray is a primary ray, the reflected main ray is a primary ray once again, and the scattered rays are secondary rays.
