Monochromator-interferometer combination for submillimeter astronomical spectrometry from aircraft.
A simple interferometer placed in front of a liquid helium cooled grating instrument was constructed; we have attained a spectral resolution of ?0.1 cm(-1) in the wavelength range of ~64 cm(-1) (157 microm) during observations from the NASA Kuiper Airborne Observatory. Spectra obtained on the planetary nebula NGC 7027 are shown.
