Abstract: An improved, multicolored video imaging system to provide a video image on a projection surface, which system includes a red, blue and green pulsed laser as a light source to provide inlet beams, an acoustic-optical cell to receive the inlet beams, an electrical signal to a sound transducer on the cell to provide a sound-modulated outlet beam; a projection surface to display the multicolored image and a projection system to project the outlet beam onto the projection surface to display the video image. The system includes as an improvement a solid state actuator to move a distance in a 45.degree. direction to backtrack the line of image of the outlet beam and a ramp signal device to provide a ramp signal that is proportional in time to the pulse duration of the input beams when the pulse duration is longer than the pixel propagation time for a line of image to be displayed, thereby minimizing the blurring of the line of image displayed.

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.

Abstract: A video imaging system is disclosed. The system is responsive to electrical signals introduced into it, which electrical signals represent an image. The system includes an acoustic-optical cell, the cell including an anisotropic medium for sound transmittal. The electrical signals are received, and optionally compressed, before being introduced into transducers mounted on the cell. The transducers convert the electrical signals into sound waves which traverse the width of the cell. After substantially a full line of display of the image is traveling through the cell, a monochromatic light source, such as a metal vapor pulsed laser, is pulsed for a time duration less than the propagation time of a single pixel across or transverse to the sound signal in the cell. This modulates the monochromatic light which is then focused and displayed on the screen at the appropriate position for the line of image.
