Abstract

This article explores the possibility of using multicriteria applied to the ray tracing result processing method to improve the efficiency of performing groups of repetitive calculations. If the usual ray tracing criterion is a filter that passes rays in accordance with some condition, usually a series of events that must happen to the ray by the time it reaches the radiation receiver, then multicriteria contains not one criterion, but a set of criteria, each of which is assigned to certain result of the calculation. The proposed concept of multicriteria was developed to solve the problems of scattered light analysis in optical imaging devices. Existing mechanisms make it possible to find sources of stray illumination of an image, but they only show the average value of stray illumination formed by an element of an optical device. In most cases, it is necessary to know the nature of the distribution of stray illumination in the image. Using the concept of multicriteria allows you to effectively solve this problem. Within the framework of one computational process, criteria are formed that correspond to the detected scattered light sources, and each of the criteria is associated with its own image. Using a special technique of ray tracing and processing of ray tracing results, separate results are generated for each of the criteria. This technique can be used not only for the analysis of scattered light, but also for modeling multichannel and multiconfiguration systems. The paper presents the results of scattered light simulation in two optical devices and virtual prototyping of the GP-200 goniophotometer.
