FIELD: engineering of systems for reproduction of television images, namely, colored video projection engineering.
SUBSTANCE: full exclusion of electro-mechanical device. Video projector contains three lasers with light radiations of three main colors, optically connected to adder of these radiations and scanning block, which is made in form of scanning electromagnetic system, which contains a block of projection optics. Modulation of brightness of radiation is performed directly in emitters of laser radiation.
EFFECT: increased reliability, reduced laboriousness of manufacture of video projector, increased quality of image.
