In this work holographic reflection gratings were stored in a PVA/acrylamide photopolymer. This material is formed of acrylamide photopolymer which is considered interesting material for optical storage applications such as holographic memories. The experimental procedure for examining the high spatial frequency response of this material is explained and the experimental results obtained are presented. With the aim of obtaining the best results, the performance of different material compositions is compared.
