LASER PROJECTOR Russian patent published in 2002 - IPC

FIELD: laser equipment. SUBSTANCE: invention is related to devices which control radiation by control over device placed inside resonator. Invention is employed as laser projector for superlarge screens. Proposed laser projector has radiation source in the form of laser, self-matched optical resonator, spatial-time light modulator built on liquid crystal and placed inside resonator forming two-dimensional matrix of pixels and lens. Converter of two-dimensional matrix of pixels ( for instance, light-fiber converter ) to strip of pixels is located between spatial-time light modulator and lens. Deflector, for example, mirror drum whose turn is timed to radiation source is additionally mounted between lens and screen. EFFECT: potential for generation of high-quality images on superlarge screens. 2 dwg
