Monochromator-interferometer combination for submillimeter astronomical spectrometry from aircraft
Abstract
A simple interferometer placed in front of a liquid helium cooled grating instrument was constructed; a spectral resolution of not less than 0.1/cm in the wavelength range of 64/cm (157 microns) was attained during observations from the NASA Kuiper Airborne Observatory. Spectra obtained on the planetary nebula NGC 7027 are shown.
