Micro-Holograms in a Methyl Red-Doped Polymer-Dispersed Liquid Crystal (E48:PVP)

N. P. Hermosa II, M. R. H. Daza


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