Device for Visualizing Infrared and Millimeter Radiation

Abstract

The design of a device for visualizing and measuring the power density across the section of a beam from sources of infrared and millimeter radiation based on metal–dielectric film structures is proposed. For the first time, experiments on recording radiation from magnetrons with operating wavelengths of 2 and 3 mm are carried out. The performance parameters of the device are determined. Photos of the device screen are presented which show the dynamics of change in isothermal surfaces of the radiation beam cross section. Fields of application of the device are recommended.
