Abstract

A cryogenically cooled dual optical channel interferometer-spectrometer is being developed by the Space Dynamics Laboratory at Utah State University (USU). The design presented is based on a standard Michelson interferometer implemented on a flexural pivot parallelogram carriage with dual beam splitters and a single drive system. The sensor will be used to make simultaneous measurements of atmospheric emissions in the 2- to 22-μm spectral range from a rocketborne platform. The dual optical channel design allows optical materials and throughput to be optimized for narrower spectral ranges, resulting in improved performance. Other enhancements resulting from the use of a dual optical channel over the single channel design are presented.
