METHOD OF FULL-COLOUR LASER IMAGE PROJECTION Russian patent published in 2025 - IPC G02B27/18 H04N5/74 

FIELD: laser projection methods.

SUBSTANCE: full-colour laser image projection method, according to which the full-colour laser image is formed by light emissions of laser beams of three main colours – red, green and blue, optically connected to an adder, to the laser excitation control inputs connecting the image colour components signals from the personal computer video adapter, the adder light signal is transmitted to the optically interfaced projection optics unit, scanning unit is made in the form of a rotary platform with a mirror on one side of the platform, an electric current conductor in the form of annular turns located along the perimeter of the platform, and a rotary mechanism in the centre of gravity of the platform on the opposite side, platform is placed in a magnetic field generated by a system of electromagnets surrounding the platform, horizontal and vertical scanning signals from outputs of a microcontroller which is controlled by vertical and horizontal scanning signals of a personal computer video adapter are transmitted to a scanning unit.

EFFECT: reducing the weight and dimensions of the scanning unit and increasing the efficiency of the scanning unit.
