Abstract
This paper is devoted to a mathematical description of a multielement radiation source with controllable chromaticity. The shape of the spatial irradiance distribution at a given distance from the source is determined in the proposed model by the number and relative placement of its elements, by the functions that describe the optical characteristics of the elements, and by the distance from the multielement source to the analysis zone (a screen, the working zone, etc.). A combination of the distributions of three color components—red, green, and blue—is used to model the radiation source, which includes emitting elements with various radiation spectra, and to obtain a model of the color diagram in the analysis zone.
