FIELD: projection systems.
SUBSTANCE: projection device includes light source, collimating optical system, at least one amplitude modulator, at least one scanning element, correcting optical system, polygonal mirror, rotary optical element, screen mirror and dissipating screen. Polygonal and screen mirrors are made in form of arrays of micro-mirrors, and number of positions of light beam at outlet of scanning element, composing a two-dimensional structure, is equal to number of micro-mirrors of polygonal mirror and number of mini-mirrors or screen mirror.
EFFECT: decreased dimensions, improved image quality.
