Optical Systems Contamination and Degradation II: Effects, Measurements, and Control.
The goal is the Active Cleaning for Space-systems (ACES) project is to develop and demonstrate a new means for on-orbit cleaning of particle contaminants from optical surfaces on satellites. This paper describes the rationale for on-orbit cleaning, a

Space optical systems operating at cryogenic temperatures may have stringent contamination levels due to high off-axis rejection requirements for the optics. The extreme difficulty in launching and maintaining clean cryogenic optics on-orbit is allev

The location of particulates in and about a telescope assembly after jet spray cleaning of a contaminated primary mirrorsurface under vacuum conditions is determined. The Pathfinder experiment described here is designed to track both thelocation and

Many Hughes Aircraft space optical sensors are very sensitive to scatter from their optical surfaces. Along withbeing fabricated to tight specifications, each optical component in the sensor must be maintained to stringent cleanlinesslevels throughou
