Abstract
The holographic storage characteristic of a new kind of photopolymer co-sensitized by two dyes is studied.The photopolymer is composed of acrylamide and methylenebisacrylamide as monomers, polyvinylalcohol as the polymeric matrix, Eosin Y and Methylene as mixture photoinitiators. Diffraction efficiencis of the photopolymer at four wavelengths are no less than 25% and 54.8% in maximum. Four different images are stored in the same dot of the photopolymer film by the multi-wavelength holographic storage method, and these images can be reconstructed clearly.
