Abstract

A unique flexural pivot mirror translation system was used in the fabrication of a cryogenic Michelson interferometer spectrometer. Uniform cooling was obtained by placing the interferometer inside a convective atmosphere within a liquid nitrogen dewar. The interferometer was flown as part of the EXCEDE SPECTRAL rocket payload which also included electron accelerators to produce artificial auroras. The interferometer successfully measured infrared upper-atmospheric emissions within the spectral range 2.0 to 5.6 μm as induced by the pulsed electron accelerators. Observed emissions include the N2 Wu Benesch infrared system, the N₂ McFarlane infrared system and CO₂. In addition, H2O outgassing from the payload was observed. The 2 cm^-1 spectral resolution of the interferometer clearly assisted in the unique identification of the dominant emissions based on their characteristic molecular band profiles.
