DEVICE FOR COLOUR PATTERN BUILDING IN INTENDED DIRECTION OF COLOUR SPACE Russian patent published in 2015 - IPC A61B3/06 

FIELD: medicine.

SUBSTANCE: invention refers to medical equipment. A device for colour pattern building in an intended direction of a colour space comprises optical channels with standard and test colour stimuli shaping units, an assembly for the colour stimuli timing in a visual field of a person being tested; the device also comprises red, green and blue light sources mounted behind each of the screens. The test colour stimulus shaping unit comprises a source pulse ratio regulator, outputs of which are connected to control inputs of a test field PWM modulator, whereas inputs of the regulator are connected to outputs of m and n pulse ratio calculator; the outputs of the ratio calculator are connected to controllers of chromaticity coordinates x₁, y₁, x₂, y₂, x₃, y₃ and a direction angle α of the generated light.

EFFECT: using the presented device is expected to improve diagnostic accuracy in various forms of colour-blindness, to increase the quantity of generated colours and accuracy in reproduction.
