Optimization of a holographic memory setup using a LCD and a PVA based photopolymer

摘要

Holographic data pages were stored in a PVA/acrylamide photopolymer. 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. During the storage process, some parameters like exposure time, beam ratio and intensity were controlled to obtain high quality images after the reconstruction process. The bit error rate was calculated to determine what parameters improve the quality of the image.
