| Note(s): | PATENT STATUS: Granted. Apparatus for horizontally scanning an image corresponding to electronic video input information utilizing a Bragg Diffraction cell in which collimated light from a laser directed through the cell is modulated by a realtime fourier transform of a line of video input information, thereby to produce a one line acoustic hologram in the cell which is reconstructed at a infinity as a stationary image corresponding to the horizontal line of video information. Using a suitable lens system, the stationary image is re-imagined at a plane positioned at a fixed distance from the Bragg Diffraction cell. The scanner is useful in image projection systems, in which the horizontal line image is vertically scanned by a galvanometer driven mirror vibrating in synchronism with the vertical blanking interval of the input video. | |
