Abstract
A full color hologram is made by exposing a holographic emulsion to the 514 nm and 458 nm lines of an argon laser and the 413 nm line of a krypton laser. The hologram can be returned to its original thickness and used as a master with the same three wavelengths, or it can be swelled to longer wavelengths to reconstruct with red, green and blue light. The source of the red, green and blue information may be acquired by an electronic video signal displayed on an electronic image modulator.
