Abstract
A multiplexed, multicolored video imaging system which comprises a plurality of pulsed lasers to provide input beams, a single acoustic-optical cell to receive the input beams, a transducer to modulate the input beams in the cell, a signal generator to produce sound waves in the cell corresponding to the electrical signals used for a line image; data compressor to decrease the time of propagation of the sound waves in the cell; multiplexer to provide an electrical signal corresponding to each wavelength to separate and sequentially modulate the video signals to provide a multiplexed, modulated output beam, a projection surface and projector to form a line multiplexed, multicolored output on the projection surface.
