Paper Abstract

Requirements for limb emission measurements have led to the design of a cryogenic Fourier transform spectrometer which combines a number of features for the first time. The critical design considerations were interferometric fringe visibility and interferogram sampling accuracy. The features include a parallelogram scan mechanism with flex pivots, a beryllium scan carriage with back-to-back cat's-eye mirrors, an optimized scan turnaround profile, a flexure-mounted KBr beamsplitter, and linear phase filtering. The instrument, which is currently under test at Perkin-Elmer Corporation, will serve as a breadboard for future spaceborne atmospheric sensors.
