Abstract
The paper presents the parameters and the results of investigations of basic subassemblies of heterodyne detection systems of scattered radiation. Work on heterodyne radiation of infrared radiation, conducted in MUT from 1983, allowed us to develop several measurement systems, based on fundamental subassemblies developed in Poland. The sources of radiation are sealed-off carbon-dioxide lasers, frequency transformation is accomplished by means of acousto-optic modulators, the compression of pulses in dispersive lines, based on surface acoustic waves (SAW) is the heart of the detection systems.
