Abstract

Feasibility of a holographic point-by-point storage in a methyl red doped Polymer Dispersed Liquid Crystal is determined. Micro-holograms (gratings) are recorded next to each other. Smallest grating diameter obtained is 69.9 μm with minimum grating distance of 80 μm. Recording of adjacent grating reduces the diffraction efficiency of existing grating by 17% (average).
