Abstract

A terahertz (THz) Fabry–Perot scanning interferometer designed to measure the wavelength and intensity of narrow-band THz radiation, as well as to filter it, has been developed. Measurements have been carried out confirming the possibility of using the device in the entire THz range. The characteristics of various modifications of FPI are given.
