摘要

This paper presents an investigation on the preparation and characterization of thick photopolymers for display holograms recording at 532 nm. Based on our previous research on fabrication and characterization of the doped photopolymer for volume holographic data storage, we develop a new large size Irgacure 784 doped epoxy resin photopolymer plate for display holograms recording in this research. The material system consists of two sub-systems. The first one is the epoxy resin polymer matrix, which provides a strong material structure so that the optical induced shrinkage during hologram recording can be minimized. The second part consists of photosensitive elements, which are uniformly dispersed in the epoxy resin to provide a mechanism for holograms recording. Material fabrication technique and the characteristics including absorption spectra, dynamic range and recording sensitivity are reported in this paper. Successful recording and reconstruction of a Fresnel hologram of the transmission type in a photopolymer plate of size 20 cm × 30 cm demonstrates the feasibility of display holograms recording in this material.
