Novel Updatable Photorefractive Type Color Holography Material and Display Development

Abstract

Recently, with need for displays which are capable of creating dynamic holographic images, various approaches to reach such holographic imaging have been explored, but many technical issues still need to be overcome and breakthrough. We have been engaged in the development of materials from the viewpoint of novel and refreshable recording materials. We particularly focused on organic polymerbased photorefractive (PR) materials which are inexpensive to produce and easy to fabricate large area display medium. Here we describe a new holographic 3D display based on a novel PR material capable of refreshing images based on both CW and Pulsed laser holographic recording techniques. We also demonstrated multi-color capability by using angular multiplexing, full-parallax image, and “Telepresence” approaches. Thus, new type of hologram medium and system can be expected to accelerate unprecedented 3D imagery system.
