Paper Abstract

A holographic polymer-dispersed liquid crystal (HPDLC) thin film is composed of multifunctional acrylate monomer blended with the nematic liquid crystal mixture, and then investigated the real-time diffraction efficiencies for various physical parameters of amount of liquid crystals and applied AC electric fields. It is experimentally shown that the holographic gratings recorded in HPDLC film can be reversibly erased and reconstructed by switching on and off of appropriate applied AC electric field. By using these electro-optic properties we have developed bifocal holographic lenses having two different focal lengths of 300 mm and 400 mm.
