Integral hologram revolving lamp and method for making same

摘要

An illuminated colored display device provides a 360-degree viewable hologram, having the properties of a distortion free, monochromatic or full-color reconstruction from a single white light source, an extended vertical viewing aperture, and extended moving scene. These advantageous properties are provided by a rotating display device and a type of "synthetic" hologram composed of movie film frames or digital information. 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. The component holograms themselves are vertically focused so that the composite hologram is white light viewable. The disclosed method includes the provision of a novel optical film holder and transport system.
