  • Patent number: 8786925
    Abstract: A method for producing and replaying a color holographic image. The method includes multiple hologram films, each film containing content replayed at a viewing angle or range of viewing angle in primarily one or more replay color(s), replay being caused by reference beam(s) of substantially the film's replay color(s) incident upon the film at reference angle(s) outside the viewing angle(s). The method also includes angularly-dependent color filters between the hologram films. Each filter substantially transmits the replay color(s) of preceding hologram film(s) within the viewing angles, blocks the replay color(s) of succeeding hologram film(s) within the viewing angles, transmits the replay color(s) of succeeding hologram film(s) at angle(s) close to the replay angle(s) of succeeding hologram film(s), and blocks the replay color(s) of the immediately preceding hologram film at angle(s) close to the replay angle(s) of the immediately preceding hologram film.

  • Publication number: 20110261427
    Abstract: A method for producing and replaying a composite color hologram, the method comprising recording a first hologram containing primarily a green content of an intended composite hologram using a substantially collimated recording reference beam, recording a second hologram containing primarily a blue content of the intended composite hologram using a substantially collimated recording reference beam, recording a third hologram containing primarily a red content of the intended composite hologram, transmitting, using a first filter, at least a portion of wavelengths close to Ar at a broad range of angles about an intended viewing angle of the intended composite hologram, blocking, using the first filter, at least a portion of wavelengths close to Ar at angles close to Or, transmitting, using the first filter, at least a portion of wavelengths close to Ab only at angles close to Ob and/or Ag only at angles close to Og

  • Publication number: 20100290099
    Abstract: A method and apparatus for recording and displaying a radially multiplexed hologram is provided. A master hologram is recorded with individual views or frames, arranged in a specific radial pattern and in such a proportion that the convergence of the individually recorded views are simultaneously combined and recorded onto a second hologram. When the second hologram is illuminated by a correctly designed light source a free floating image projecting above the platform on which it was recorded is displayed. The rotating platform presents sequential views to a fixed viewer, creating a moving image.
