Popis:	Multiple-window acousto-optic filtering of wide-band (white) light allows to control chromaticity of radiation in the visible range, which allows to use a system consisting of a source of radiation and an acousto-optic filter for colour reproduction problems, for instance, in colorimetry, psychophysiology, spectral analysis, biomedicine and other applied and research areas requiring radiation chromaticity control. The article describes the problem of reproduction of a necessary colour when using two or three spectral components (narrow bands), evaluates the factors affecting accuracy of colour reproduction and demonstrates the capability to reach errors below the chromatic threshold. Also it demonstrates the capabilities of reproduction of colours close to chromaticity locus in the multi-frequency mode of an acousto-optic filter.
