The Experimental Research Installation for the Determination of Monochromatic Thresholds of Human Visual System

Abstract

Relying on the statistical theory of the human threshold colour vision, the authors have developed the method how to determine the colour-matching functions of the physiological colorimetric system (LMS)phys. To implement the developed method, the authors have created the experimental research installation that allows them to determine the threshold characteristics of the visual system during the observation of monochromatic objects against coloured backgrounds. The authors have studied the inaccuracies of the experimental installation and of the algorithm for solving a system of nonlinear equations that allows them to determine the colour-matching functions of the physiological colorimetric system according to the results of the experiment.
