Paper Abstract

A system for detecting and removing contaminants from a half-meter diameter primary mirror in a simulated space telescope has been designed, fabricated, and tested under vacuum conditions. Various molecular and particulate contaminants are deposited on the mirror by special sources in the open end of the telescope, causing an increase in optical scatter which is detected at infrared wavelengths by special sensors on the wall of the telescope. Depending on the type of contaminant, either of two systems of contamination-removal hardware is activated to clean the mirror surface and restore the original scattering level.
