A heterodyne detection system for the submillimeter wavelength range from 100 μm to 1000 μm is described, using a laser as local oscillator, a Schottky barrier diode in an open structure mixer and an acousto-optical spectrometer. This paper summarizes recent research on a high resolution heterodyne spectrometer and its applications in astronomy and atmospheric physics. The detection of carbon monoxide lines 12CO at 370 μm and 430 μm and of the 13CO line at 910 μm demonstrate the instrument's capabilities.
