Three-dimensional imaging and display of real-existing scene using fringe

Holography, in which three-dimensional (3D) information and texture of object is encoded with interference fringe is a promising approach for 3D display. However, it is challenge to make photographic hologram of living object. In addition, it is impossible to record scene combining real-existing objects with virtual ones using photographic holography. In this paper, we propose a method for capturing and displaying 3D real-existing scene. Firstly, the 3D shape and color texture of scene is captured with fringe projection method. Secondly, the information of scene is encoded with computer generated fringe, which is called Computer-generated Hologram (CGH). Finally, the CGH is materialize as hardcopy or transferred to spatial light modulator (SLM) for display. The real-color Rainbow-hologram is chosen for display static scene. Three Fresnel holograms corresponding to red, green and blue component of scene are adopted for display dynamic scene. The apparatuses for 3D capture and display are introduced and the experimental results are demonstrated.
