Abstract

The Fabry-Perot spectrometer designed for NIR spectroscopic observations on the Balloon-borne Infrared Telescope (BIRT) is described in detail. Particular attention is given to the newly developed frequency switching method used in the BIRT, which is especially suitable for observations of spatially extended emission because the frequency switching mode does not require spacial chopping. Observations are described from two successful experiments conducted in 1988 using the Fabry-Perot spectrometer on the BIRT, in both the spatial chopping mode and the frequency switching mode.
