| Displays Using Solid-State Lasers & Bragg Diffraction Intensity Controls 
Description 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 real-time 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. Advantages - Laser scanning projector without requiring a high speed mechanical horizontal scanner
- Projected image interpolates between lines to produce an image without visible scan lines
Potential Applications - Improved laser scanner system for an image projector useful for large screen display of electronic video information, such as high definition television
