LARGE-ANGLE DEFLECTION TECHNIQUE FOR LASER DISPLAY.
Abstract
A large angle deflection technique for producing a 945-line T.V. type raster scan in an experimental laser display was developed, since conventional deflection methods could not be used. The horizontal scanner was comprised of a rotating mirror and a piezoelectric cartridge, coupled by a glass resonator shaft. A circular scan was generated and then transformed into a linear scan by a fiber optic converter. The use of the fiber optic bundle allowed zero flyback time. The linear beam was then deflected vertically by a galvanometer driven mirror at a 60 cycle per second rate. After vertical scanning, the light beam was projected through a lens on a screen. Circuitry for error sensing feedback for the scanners is continuing under study. (Author)
