Different Dye-sensitized Photopolymer Materials

In recent years, photopolymer has been used as multifunctional holographic medium and there are more and more applications in holographic data storage, holographic display, optical microelement, wave-guide and other fields of optical processing and display. Compared with other holographic materials such as holographic silver halide plate and dichromate gelatin, the obvious advantage is no wet processing. In addition, photopolymer has such advantages as low cost, high sensibility, good stability and long shelf life over inorganic photorefractive materials, which make polymer_more promising in commerce and manufacture. Some certain components can be added to optimize optical properties to satisfy some special requirements. After the review of the principles of photo polymerization, kinetics of holographic recording in photopolymer and the basic components of the photopolymer materials, we have studied the contents as follows:1. During the sample preparation, we use triethanolamine as radical generator , acryl amide(AA) and N, N' -methylene bias acryl amide(BAA) as monomers , erosion Y, Methylene Blue, erythrosine as sensitizers respectively, all on a film of polyvinyl alcohol, obtaining green sensitive , red sensitive and...
