Your library or personal account may give you access

Abstract

The FIRS-2 is a far- to mid-infrared Fourier transform spectrometer, designed and built at the Smithsonian Astrophysical Observatory for the purpose of measuring stratospheric emission spectra. The instrument and data reduction system have been described elsewhere [Johnson et al., 1994]. We present here the method we have developed for phase recovery from highly asymmetric interferograms in the presence of an out-of-phase background signal.
