Abstract:

Photopolymer is an optimum material for practical holographic storage because of low cost and good characteristics. A new epoxy resin-photopolymer is reported. Polymeric binder is epoxy resin whose refractive index is high, but the monomer's refractive index is relatively low. The design can make monomer transfer freely in rigid frame, so we can realize no-shrinking recording and stabilize the recorded hologram. Simple grating is recorded in films, then we obtained the relationship curve between the exposure energy and diffraction efficiency by sending a single beam into the photopolymer film. According to the exposure curve, there is a recording delay, so the pre-exposure is needed to sensitize the material. In order to avoid cross-talk between contiguous holograms, angle selectivity of the material is measured. Then we investigate how diffraction efficiency is distributed in all multiplexed holograms with equal-time exposure. One method of calculating exposure schedule for multiplexing holograms in photopolymer with equal efficiency is presented. By using such exposure schedule, holograms are recorded at a single location by angle multiplexing, and the uniformity of their diffraction efficiency is remarkably improved. After iterating the procedure, it is possible to achieve much more uniform diffraction efficiency.
