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.
