ABSTRACT:
A new class of holograms, having the properties of full-color reconstruction from a single white light source, an extended vertical viewing aperture, and extended scene depth is disclosed. These advantageous properties are provided by a hologram composed of three intermeshed holograms, each of which reconstructs only one of the three color components of the scene. Each color component hologram consists of an array of noncontiguous small dots or thin stripes so that the three-color component holograms may be intermeshed without overlap of the dots or stripes. Associated with each color component hologram is a similar array of dot or stripe color filters which allow only the appropriate color of light to reconstruct each color component hologram. The component holograms themselves are vertically focused so that the composite hologram is white light viewable.
