The Technique Of Making Color Large Scale For Fresnel Digital Stereogram

Color display holography, which is the most accurate imaging technology known to science, has been used to produce holographic images for display of artifacts in museums. This article presents the ’Bringing the Artifacts back to the people’ project. Holograms of twelve different artifacts were recorded using the single-beam Denisyuk color reflection hologram technique.on DNP website has information about digital hologram products.A large scale Fresnel holographic stereogram is achieved based on holographic stereogram automatically recording designed and manufactured by the optical information processing and holography laboratory in Ocean university of china.It is used to handle digital images that includes maya,photoshop and matlab.This paper try to solve the harassed problem that usually occurred when use multi-beam laser to illuminate Hologram.The thesis is composed of five parts.The frist part introduces the development of Digital holography.The second part mainly expounds the principle of stereogram and processing method. The third part expounds experimental process in detail, including confirming the project, parameters and model,image processing, recording holographic units and the completion of large hologram.The forth part analyses the experimental result,through the analysis of vision field and image quality,explains whether the technology is feasible,and discussed the problems occurred in the experiment with the corresponding improving method.The fifth part summarizes the experiment and takes glance of the future work.
