Abstract
Some techniques have been developed for color hologram recording on photographic film. These techniques are applicable to the rainbow hologram1 and the white-light reflection hologram.2 In this paper we demonstrate the recording of color holograms in photorefractive media. The photorefractive crystal is thicker than the photographic emulsion and therefore provides a higher wavelength selectivity for the recording of color holograms. Multiple storage of color holograms is impossible in emulsion.
