Abstract

A novel method for measuring the intensity profile of far-infrared radiation is presented. The idea is to measure nonstationary thermally induced variations in optical thickness of a target heated by the studied radiation. The optical thickness variations are observed by an interferometer. Beams with an aperture up to 60 mm may be measured with a spatial resolution of I mm.
