  • Patent number: 6072545
    Abstract: An image rotating apparatus presents a projected video image upon a rear projection screen that is rotated extremely rapidly about a vertical axis which exactly bisects the picture in the vertical plane. The rotational rate is such that an entire audience, regardless of their position about the apparatus, can view the projected video image simultaneously. The video image rotating apparatus utilizes light valve technology to create red, green and blue images from an analog composite video signal, and a Phillips prism that aligns the images produced by the light valves for projection through an optical system. The image produced by the light valves is rotated, either mechanically or electronically, in synchronization with rotation of the projection screen.

  • Patent number: 5018007
    Abstract: A relatively thin projection screen includes a sheet of parallel, specially treated fiber optic cables that emit light transversely, and an overlying liquid crystal display screen formed of a plurality of adjacent and individually modulatable liquid crystal shutters. A dot matrix of pixels is generated by controlling the sequential transmission of light to the optical fibers, and the transparency or opacity of the overlying shutters. As each row of the optical fibers is sequentially energized by a light source, the columns of liquid crystal shutters are simultaneously opened or closed in accordance with signals derived from a television video signal. This provides an optical reproduction of the television signal from the pixels of light defined at the cross over points of the rows and columns. The liquid crystal shutters are modulated to allow a varying amount of light to pass through so that different levels of brightness may be obtained.

  • Patent number: 4979026
    Abstract: A viewing system is provided for presenting a real image in space that is rotated extremely rapidly so that an entire audience, regardless of an individual's position about the viewing system, can view the same image substantially simultaneously and continuously. An electronic image rotation system distorts, processes and rotates an image upon a cathode ray tube (CRT), and a parabolic mirror arrangement projects the image from the CRT to provide a rotating real image in space. A rotatable polarized screen and a separate, stationary polarized screen cooperate to define a viewing window which remains continually aligned with the rotating real image in space.

  • Patent number: 4943851
    Abstract: A viewing system is provided for presenting a projected image upon a rear projection screen that is rotated extremely rapidly about a vertical axis which exactly bisects the picture in the vertical plane. The rotational rate is such that an entire audience, regardless of their position about the viewing system, can view the projected image simultaneously. The 360.degree. viewing system features an optical system which rotates with respect to a cathode ray tube about the vertical axis in synchronization with the rotation of the projection screen. A liquid crystal display (LCD) screen is utilized to define a viewing window which is continuously redefined at sequential intervals to remain continually aligned with the projection screen.

  • Patent number: 4901140
    Abstract: A viewing system is provided for presenting a real image in space that is rotated extremely rapidly so that an entire audience, regardless of an individual's position about the viewing system, can view the same image substantially simultaneously and continuously. An electronic image rotation system distorts, processes and rotates a black and white image upon a cathode ray tube (CRT), and a parabolic mirror arrangement projects the image from the CRT to provide a rotating real image in space. A liquid crystal display (LCD) screen is utilized to define a filtered viewing window which is continuously redefined at sequential intervals to remain continually aligned with the rotating real image in space. The LCD screen includes normally opaque red, green and blue filter panels which operate to give color to the real image in space.

  • Patent number: 4578709
    Abstract: A flat TV screen is provided by overlapping rows and columns of fiber optics. Each cross-over point will emit more light than radiates from the side of a single optical fiber when both of the crossing fibers are energized. Therefore, a dot matrix can be generated by controlling the entrance of light into the ends of the optical fibers in the rows and columns. The rows of optical fibers are sequentially energized by a light signal of constant brightness. The columns in turn are successively energized during the time period that each row is energized with signals derived from a TV video signal to thereby provide an optical reproduction of the TV signal from the dot matrix of light defined at the cross over points of the rows and columns.

  • Patent number: 4344671
    Abstract: The assembly includes a plurality of individual pulse lasers arranged to be successively triggered at predetermined time intervals. A single light transmissive body receives the output pulses from the lasers at different input angles so that the respective pulses follow different path lengths in the body. The sequence of firing of the lasers and the respective angles are such that pulses exiting from the body will all exit substantially simultaneously. The result is a high energy concentration of output light.

  • Patent number: 4345184
    Abstract: The entrance ends of a plurality of optical fibers are arranged in a circular array and each provided with light emitting material in the form of phosphor responsive to impingement of an electron beam. The circular array of the fiber optic entrance ends is scanned by an electron beam so that the light emitters are successively triggered, the time for light to travel the difference between successive light paths defined by the optical fibers corresponding to the time of scan from one light emitting phosphor to the next adjacent light emitting phosphor so that individual pulses of light exit from the ends of said fibers substantially simultaneously.

  • Patent number: 4311357
    Abstract: A laser beam is scanned in a circular pattern so that it will successively impinge upon light entrance ends of a plurality of optical fibers arranged in a similar circular array. Successive fibers differ in path lengths in such a manner that the light from the scanning laser beam exits substantially simultaneously from the exit ends of the fibers so that a relatively high intensity or amplitude light pulse results.

  • Patent number: 4264135
    Abstract: A steady light beam such as continuous wave, constant amplitude coherent light as provided by a laser, is moved through a given acute angle at a given frequency. The light beam is passed into a solid body of light transmissive material while moving through the given acute angle such that the initially received light in the body when the beam starts its movement through the acute angle follows a first path of a first given length before it emerges from the body. Subsequently received light in the body when the beam has completed its movement through the acute angle, in turn, follows a second path of a second given length different from the first given length before it emerges from the body. The referred-to-frequency is adjusted to define a time increment for the beam to move through the referred to given acute angle. This time increment is made substantially equal to the time it takes light to travel a path length in the body equal to the difference in the referred to first and second given lengths.
