Abstract: Holography with a red sensitive photopolymer system is described. Our photosensitive medium is composed of a sensitizer, initiator, monomer, inhibitor, and polymeric film-forming binder. This is a type of phase holographic recording material, using wet developing and fixing method. The material has high diffraction efficiency, high resolution, and higher sensitivity. It possesses advantages of both silver plate and dichromated gelatin plate. !5
