Abstract
A flexible liquid crystal hologram was prepared as a novel type of holographic materials. Polycarbonate films covered with a polyimide were employed as a substrate, and toluene solution of a polymer azobenzene liquid crystal (PALC) was coated on the rubbed substrate, resulting in a flexible PALC film. We attempted the formation of gratings and holographic image storage of 3-D objects into the flexible film. A clear and bright 3-D image was successfully reconstructed even in the bent film. This indicates that the holographic diffraction grating is formed in the flexible PALC film.
