Stray radiation in optical systems II; Proceedings of the Meeting, San Diego, CA, July 20-22, 1992
Abstract
Various papers on stray radiation in optical systems are presented. Individual topics discussed include: ultralightweight beryllium mirror development; imaging incoherent, off-axis, scattered radiation; correcting for diffraction in the FIR reflectance measurement of rough surfaces; effect of jet-engine exhaust on SOFIA stray-light performance; specular baffles; wavelength dependence of scatter in chemical-vapor-deposited SiC; selection processes for black baffle surfaces in optical systems; PEARLSS model for contamination effects; black surfaces for space and ground-based optical systems; very near specular measurement via incident angle scaling. Also discussed are: near-specular measurements of integrated scatter; thermal emissivity analysis of a Gemini 8-m telescope design; design and on-orbit performance in the WIND II baffle system; knife-edged diffuse-absorptive and dual reflective baffles; stray-light analysis of the Cassini telescope; use of Siamese pseudoptics in APART; bidirectional reflectance data to support paint development and signature calculations; rugged dark materials for stray-light suppression by seeded ion beam texturing; Mueller matrix measurement of scattered light; unique out-of-plane polarimetric scatterometer.
