Holographic method for forming color holograms

摘要

A color hologram is recorded on a holographic recording material sequentially by use of different color coherent light beams with a stripe filter placed on the recording material and moved by a length equal to the width of the transparent stripes of the filter for each different color laser beam. The color holographic image recorded is therefore composed of stripes of different color component arranged side by side in a fixed order. The color holographic image is reconstructed by exposing the hologram simultaneously to different color reference light beams through stripe filters inserted in the respective reference light beams.
