| 摘要 |
The invention relates to optoelectronics and is used in information visualization, display, storage and processing devices and systems having a high information capacity: in two-dimensional and three-dimensional projection displays, devices and systems of optical advertising and show business. The video projector comprises a liquid-crystal micro-display based on an FLCoS structure with smectic liquid crystals, an optical unit for reading information formed in the FLCoS structure, a light source and projection optics, both being optically linked to the FLCoS structure and to a screen onto which the information is projected, wherein the material used in the FLCoS structure is low-voltage smectic liquid crystal with a compensated helicoid, providing a physically realizable, uninterrupted, half-tone, anhysteretic modulation characteristic by virtue of a certain proportional relationship of parameters, lasers emitting red, green and blue light serve as a light source in three different RGB color channels, the unit for reading information is provided with a cell with smectic liquid crystal in order to prevent the three types of light from creating interference, said cell performing rapid electrically-controllable spacial phase modulation of the light, and a two-dimensional scanner is provided for the formation on the screen of information files with differing geometrical configurations, said scanner being optically coupled with the information reader unit and the screen onto which information is projected. |
