Calculation of spatial distribution of energy of a complex radiator

The paper presents the results of calculating spatial distribution of radiant energy from a radiator consisting of a cylindrical source of radiation and two disk reflectors, accordingly, with a diffuse character of radiation and reflection. A program of modeling optical parameters of complex reflectors is used as the basic tool of calculation. The basis for the procedure applied is the iterative-zonal method the essence of which consists in separating the radiating and reflecting systems as well as the light-trapping hemisphere into mentary platforms. The exchange of energy between the platforms is defined by means of a forward stroke beam method. The results of calculation are compared to the experimental data obtained in the course of the model light experiment.
