Polymer used as holographic recording materials: a review

Optical processing and computing applications require practical recording materials with certain advantages such as real-time capability high-resolution and stability against environmental changes. Organic materials are one class of recording materials well suited for information storage. This presentation gives an historical review of holographic materials used to record holograms. Some basic aspects of holography also are given to complete the presentation. Some discussions of the photophysics and the photochemistry involved during the recording of light patterns are also presented. Finally, some applications in the fields of dynamic holography, write-once holography and optical data storage are presented.
