Spatial light modulators in by-page volume holographic memory architecture

The role and place of the spatial light modulators (SLM) in holographic memory devices (HMD) with by-page data storage have been estimated. The conditions under which the SLM characteristics are optimized for the information input into HMD, have been considered. It has been shown that it is not enough to make the demands to the SLM harder but it is necessary that they would not be set too high.
