Abstract
The possibility of conversion and registration of high intensive radiant flows by transverse thermo-emf arising in anisotropic media with different degrees of optical transparency has been studied. The basic expressions for the studied opticothermoelements as well as thermogenerators and receiving devices based on the use of the “transparent wall” method have been obtained. The possibilities of practical use have been analyzed and the demands on materials properties have been determined. The investigation results have allowed a method of high density radiant energy registration to be proposed. The device performances (volt-watts sensitivity, limit sensitivity, time constant, registration power limit value, optical transmissivity) have been obtained from the heat balance equation. Some constructions of optical and infrared wavelength radiant energy measuring devices have been produced
