面向全息三维显示的氧化石墨烯聚合物全息特性研究

One of the fundamental issues with holographic 3D display is to find a practical holographic material. In this research, graphene-oxide polymers are chosen as holographic materials to be explored. Theoretical models of holographic graphene-oxide-based films are developed based on the combination of physics, chemistry and materials theory. We analyze a series of mechanism processes such as optical physics and photochemical reactions during optical exposure. .We will investigate the fabrication process and optimize the testing methods so as to improve the holographic performance of the material, which will be influenced by dynamic changes of the graphene-oxide particle size variation as well as the concentration distribution under pulse and continuous exposure..Specifically, holographic films with different concentration ratios of ingredients are fabricated and tested to contrast the characteristic quality. .Testing with undoped and doped holographic films with different concentration ratio of inorganic oxides are analyzed. In addition, holographic films with its optimal ratio of concentration and doping particle size are explored. Experimental holographic display system is constructed and key factors that impact the best performance of the holographic film made of grapheme-oxide polymers are discovered. We also plan to research ways to increase the phase modulation depth and the viewing angle of the optimized material. The project’s ultimate aims are to solve one of the basic problems in holography and to provide technical support for holographic 3D display..The proposed research involves novel materials and has important theoretical value and practical significance in holographic technology and three-dimensional display.
