Abstract
A technique combined domain decomposition and staged ray splitting is presented to decrease computational complexity by reducing surfaces and rays for intersections solution. Domain decomposition is based on relation between sub-zone and number of surfaces. Splitting ratio is determined with propagation information of stray light. A suppression structure and a multi-sensor system are analyzed. It shows that the technique can improve computational efficiency while maintaining acceptable accuracy.
