Abstract

An excellent instrument to observe the emission lines of OH in the far infrared is a cooled scanning Fabry-Perot (FP) where the orders are selected by means of a grating monochromator. A compact liquid helium cooled prototype has been built for airplane missions. A similar device is the OHIO instrument, proposed for limb observations from a satellite and applying detectors in conjunction with space-qualified refrigerators. Compared with heterodyne receivers, an FP at 80 K offers a comparable sensitivity in the 100 (mu) wavelength region and much better values with bolometric detectors optimized for lower temperatures. Compared to satellite-borne Fourier Transform Spectrometers (FTS), the FP instrument is more sensitive at 80 K; the FTS measures many superfluous spectral elements. The FP is superior at temperatures low enough to allow photon-noise-limited detector operation.
