This technical publication describes how to simulate stray light in optical systems using the Advanced Systems Analysis Program (ASAP®) from Breault Research Organization (BRO).
ASAP combines 3D geometrical optical and mechanical systems modeling with detailed optical properties simulations. These simulations include isotropic and anisotropic surface scatter, volume scatter, Narcissus effects, and an efficient method for modeling scattered light. ASAP also models other stray light phenomena including ghost imaging, diffraction, and thermal emission.
Summary of changes
This document received a technical review. Edits were made to some equations (5, 7) figures (2), and text for accuracy and completeness. (July 11, 2013)
On page 14, the reference to isotropic scatter models was modified to read: "ASAP also has a library of isotropic scatter models that are created by fitting measured data." (May 14, 2013)
This document received its annual technical review. Edits were made for clarity and completeness.
