Abstract
A postdispersion system for astronomical observations with Fourier transform spectrometers in the thermal infrared has been developed. Postdispersion improves the sensitivity of radiation noise limited observations by reducing the spectral range incident on the detector. The instrument is described and various uses are discussed.Keywords
