A new type of green light sensitive photopolymer material is prepared. The photosensitive medium is composed of acrylamide monomer, photoinitiator, coinitiator and polymeric film forming binder. With holograms recorded in this material, the diffraction efficiency of the photopolymer as high as 55% is obtained. 10 holograms are stored in this medium using angular multiplexing technology and the SNR of the reconstruction images is high. It proves that the photopolymer is suitable for high density volume data storage.
