Advances in the Stray Light Analysis of Astronomical Telescope Systems

摘要

The analysis of more complicated, higher performance telescopes, instruments and telescope/instrument systems has improved, through advances in the techniques of stray light analysis. These include the use of more sophisticated opto-mechanical modeling and improved assembly of stray light models. Improvements have also been made in creating more realistic scatter models for diverse surfaces, included contaminated surfaces. The large number of system;, analyzed in the last few years has also led to an improved understanding of code strengths and limitations.
