Abstract
A method is developed for analyzing the spatial distribution of a terahertz (THz) radiation beam using a developed optical beam 2D scanning system based on a pyrodetector and an automated biaxial translator. The results of measuring the spatial distribution of THz radiation generated by a microwave synthesizer in combination with frequency multipliers in the 220-330 GHz and 500-750 GHz spectral ranges are presented. The influence of the detector aperture size and parasitic re-reflections on the system elements on the recorded spatial profiles of THz radiation beams is investigated. Methods for combating the effects associated with radiation re-reflection between the source and the detector are presented.
