Human color vision is being actively studied in many areas, for example in ophthalmology, neurophysiology, in the diagnosis of various types of diseases. However, it has not yet been fully investigated due to the lack of a device (visual colorimeter) that would allow to fully cover the XYZ color space, the model of which was adopted by the International Commission on Illumination (CIE) in 1931 and refined in 1964. To be able to reproduce color in the entire XYZ color space, it is necessary to control the spectral composition of radiation, namely, to provide the transmission of a narrow spectral line in the entire visible range, and to control the number of selected spectral lines, their position, intensity and width. Such control is made possible by a polychromatic acousto-optical tunable filter. The paper considers two optical schemes of a visual colorimeter based on the polychromatic acousto-optical tunable filter for studying color vision of the standard colorimetric observer in accordance with the CIE 1931 and 1964 standards.
