George V. Boos, Ph. D., RANS Academician, Winner of the State Prize of the Russian Federation, President of ILEC BL GROUP, head of the Light-Engineering sub-department of NIU MEI, Chairman of the Science and Engineering Board of the Russian light and engineering industry, head of the Interstate Technical Committee and the National Technical Committee 332 of Rosstandart (Light Engineering and Artificial Lighting). In 1986, he graduated from Moscow Power Engineering Institute (MPEI), engineer electrician qualification, specialty in Light and Engineering and Light Sources

Using a statistical model of the threshold of colour vision, a new expression is obtained to calculate the detection probability of colour objects against colour backgrounds. The method shows that in the day sight area, this probability is completely determined by the individual criterion of decision making about an objectТs presence, by addition functions of the RGB colorimetric system, by radiance spectral concentrations of the object and background, and by the angular dimensions of the object.
