Solid state laser beam recorder for 875 line TV
Abstract
A simple and inexpensive laser recorder employing solid state deflection is designed to convert 875 and 525 line raster signals to motion pictures in supper 8 mm dry silver film. Heat development of the dry silver film is included in the recorder such that near-instant playback can be achieved through conventional motion picture equipment or by electronic raster scanning using the recorder itself as a playback machine. The system uses a 4-mW He-Ne laser, an acoustic-optic modulator to modulate the intensity of the light of the video rate, a conventional acousto-optic Bragg deflector to provide image plane scanning in the vertical direction, and a new chirp type scanner for horizontal image plane scanning. Feasibility is demonstrated and a prototype model is being constructed.
