LIQUID CRYSTAL PHOTOSENSITIVE CELLS AS A MEDIUM FOR REAL-TIME DIGITAL PROJECTED HOLOGRAMS

Abstract

The possibility of diffraction pattern generation in pure and dye-doped LC (Liquid Crystal) cells as a media was proven. Newly developed projection method of optoelectronic reconstruction of holograms expands possible applications of liquid crystals in dynamic holography. The presented works goal is to check the physical and optical parameters of isothiocyanate nematic liquid crystal mixtures and cell construction in reference to projection set-up of hologram presentation. The experimental results of holographic image registration are discussed. Sample reconstructions of synthetic holograms are shown.
