Abstract:

Two systems designed to enable the spectral measurement of the airglow in the 2 to 4 micron region have been developed. Both systems are designed for use in high-altitude aircraft. This eliminates the problem of strong thermal emission of the lower atmosphere which is encountered when making airglow measurements in the 2 to 4 micron region from the ground. In the first system the entire measurement apparatus, including the interferometer-spectrometer, is cooled in order to eliminate unwanted thermal emission. The second system incorporates the use of a cold chopper mounted outside the aircraft. This technique allows the interferometer-spectrometer to be maintained at normal temperatures.
