Abstract
The layered systems of holographic photopolymer materials for recording color holograms are designed and developed. Monochromatic and dichromatic (green-red, red-blue, and green-blue) three-dimensional reflection holograms are obtained using He-Ne, Ar+, and DPSS lasers in red, green, and blue spectral ranges. The effects of cross-discoloration of the colorants used, and the holographic properties of monochromatic and dichromatic holograms in layered systems are considered. It is shown experimentally that the diffraction efficiency of these holograms is ~(70-80 %) and comparable with that of monochromatic holograms obtained in single-layer holographic photopolymer materials.
