Abstract
We develop new visualization and diagnostics techniques for the analysis of the mechanical causes of second-order scattered light, applying these to the stray-light analysis of the MONS space telescope, whose scientific aim is the measurement of low-amplitude photometric oscillations in stars. The telescope is designed to detect amplitudes of 1 part per million, requiring a high stray-light rejection factor, and is thus an ideal subject for this work. The analysis involved determining stray-light cases and then using an innovative approach to efficient high-order ray tracing to produce detailed predictions of the stray-light flux distributions. In addition to demonstrating the utility of the approaches developed here, the results of the analysis show that the MONS space telescope design meets the stray-light rejection requirements.
