Paper Abstract

Several illumination calculation programs are available o aid in the design of electronic projectors. In this paper, two programs are compared: ASAP and TracePro. First, their capabilities are compared in a checklist. ASAP has enough features to model almost any optical system, while TracePro is a newcomer that is in the process of adding necessary features. TracePro excels at system entry and file transfer. Second, each of them is used to analyze tow electronic projector models: and early design wi a single 6.4 inch diagonal panel and a current design with three 1.3 inch polysilicon panels. Performance predictions by the two programs are similar, although ASAP traces rays much faster.
