Abstract

Now the era of big data has arrived, and there is an urgent need for high storage capacity storage solutions to store large amounts of data. As a new generation of storage technology, holographic optical storage has the advantages of large data storage capacity, fast transmission speed, read-write parallelism and so on. The storage material for holographic storage should have the characteristics of fast response, high signal-to-noise ratio, high diffraction efficiency and high stability. Phenanthrenequinone-doped poly (methyl methacrylate) (PQ/PMMA) photopolymer is a common storage material, which has the advantages of high diffraction efficiency, inexpensive and simple preparation. Currently, PQ/PMMA is mainly prepared manually. The reproducibility of the preparation process faces challenge due to human errors. Therefore, we designed an automatic PQ/PMMA preparation device, which can effectively eliminate the differences caused by human factors. We have verified through experiments that materials prepared automatically have better stability than those prepared manually. Among the prepared single sheet materials by automatic preparation device, we measured that the difference in diffraction efficiency at different positions is within 10%. The automated experimental platform provides assistance for the stable preparation of materials
