The purpose of this technical publication is to describe how ASAP®, the Advanced Systems Analysis Program from Breault Research Organization, Inc. supports the tools necessary to simulate both imaging and illumination systems. The comprehensive imaging and illumination simulation capabilities in ASAP are demonstrated by modeling a liquid crystal display (LCD) projector.
All optical systems contain both imaging and non-imaging or illumination systems. This is illustrated in
overhead, slide, and liquid crystal display (LCD) projectors. The illumination system provides light to the slide or LCD, which is then imaged to a screen by the projection or imaging system. Even an automobile headlight can be considered an illumination system with your eyes providing the imaging function.
Since all optical systems contain both imaging and non-imaging systems, any optical engineering software should be able to simulate both system types. This is necessary for complete end-to-end, seamless simulation, regardless of whether the optical software is a lens design or analysis program.
