Abstract: Holographic data pages were multiplexed in a PVA/acrylamide photopolymer layer. This material is formed of acrylamide photopolymers which are considered interesting materials for recording holographic memories. A liquid crystal device was used to modify the object beam and store the data pages in the material. Objects with different pixel size have been used to simulate the data pages. A peristrophic multiplexing method is used to store a large number of data pages in the same spot in the material. The Bit Error Rate (BER) was calculated fitting the histograms of the images to determine the quality of the images.
