Based on TMPTA two-monomer photopolymer holographic materials

In order to study the new holographic recording medium, four kinds of photopolymer materials containing TMPTA monomers are studied. The three-dimensional interference fringe information was successfully recorded in the photopolymer film samples, which proved that it has good holographic recording and high resolution ability. The experimental results show that when the recording angle is 30°, the diffraction efficiency is as high as 93.5%@532nm and the refractive index modulation is as high as 3.07×10^-3. As a holographic recording medium, it has high resolution ability and high diffraction efficiency, the material is possible suitable for permanent storage of holograms and big data, besides it has strong advantages and potential applications in the large-scale 3D display, big data storage, holographic anticounterfeiting, holographic printing and other fields.
