Title: Cryogenic optical systems and instruments V; Proceedings of the Meeting, San Diego, CA, July 23, 24, 1992
Abstract: Topics discussed in this volume include cryogenic system design and optical technology; cryogenic instruments; cryogenic/IR mechanisms, testing, and performance; and space cryogenic dewars and coolers. Papers included are on the SIRTF cryooptics technology plan, the development of the SPIRIT III sensor, the design of a rapidly cooled cryogenic mirror, the cryogenic Michelson interferometer on the Space Shuttle, a reflective optical system for a hemispherical field radiometer, and infrared filters for cryogenic radiometers. Attention is also given to the development of a variable-profile scan mirror mechanism, a direct-drive digitally commutated filter wheel positioning system for cryogenic optical applications, a high-performance chopping secondary mirror for infrared astronomy, recent developments in compressor-based Joule-Thomson cooling, a radiative cryogenic cooler for the pressure modulator IR radiometer, and SIRTF thermal design modifications to increase lifetime.
