  • 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.
