FIELD: physics.
SUBSTANCE: illumination device has an array of light emitters (11.1, 11.2) which are optionally separated by optical barriers (13). More specifically, the light emitters (11.1, 11.2) can be made from a group of LEDs (12.1, 12.2) of different colours, e.g., red, green and blue. Local control units (16), excitation units (15.1, 15.2) and sensor units (14) are provided for controlling separate luminous efficacy of the light emitters, wherein at least one of these components is shared by two or more light emitters (11.1, 11.2).
EFFECT: high efficiency of using system energy, elimination of motion artefacts.
