Thermoplastic Holograms In Optical Metrology And Image Processing

Thermoplastic photoconductor materials are conveniently used for recording holograms because of their interesting advantages, but the processing is rather delicate and making good holograms is not easy. These difficulties are surmounted by developing new techniques for processing holograms such as the post-exposure light application (PLA) method and the the solvent vapour method, and applications of thermoplastic hologram have been still more promoted. This paper presents outlines of these new techniques together with some of their applications in the field of optical metrology and image processing.
