FIELD: light engineering. SUBSTANCE: method involves following operations: formation of coherent light flux of (R), green (G), and blue (B) beams; conversion of continuous primary picture into pulsed pixels considering color and brightness distribution in primary picture; modulation of R-, G- and B-beams with respect to power and angular position in space; novelty is that upon modulation three R-, G-, and B-beams are conveyed simultaneously over single optical path to input ends of adjustable-corearrangement fiber-optic cable; all three beams are transmitted to point of pattern visualization over fiber-optic cable sequentially over its three cores so that pixel is formed across its output ends. Color laser projector has source of coherent polarized red beam R, green beam G, and blue beam B; laser R-, G, and B-beam shaping unit; unit for controlling intensity and angular position of laser R-, G-, and B-beams in space; scanning unit; scaling, focusing, and interrelated beams aligning unit; radiating screen formed by output ends of adjustable- core-arrangement fiber-optic cable. R-, G-, and B-beams arrive at output ends of cable; point of alignment of three beams is displaced by means of control unit along input ends of fiber-optic cable so that one point on output end corresponds to each point on input end. Projection system used for producing stereoscopic picture has two color laser projectors whose beams are relatively orthogonal; control units of projectors are relatively synchronized with respect to frames, and fiber-optic cables are designed to maintain direction of polarization or cables are not designed to do so; polarizer is mounted at output of each cable core. EFFECT: enhanced brightness of pixel-displaying screens; provision for reducing stereoscopic effect; reduced cost. 10 cl, 6 dwg
