Holographic recording of data using a time-dependent object beam

A system for holographic page-organized recording of data with the aid of a time-dependent phase-modulated object beam was proposed and tested. Transformation of the initial amplitude image into one modulated in phase was performed in a liquid-crystal spatial light modulator. This system made it possible to relax requirements in respect of the homogeneity of a number of properties of the modulator and in respect of the precision of its fabrication.
