Projection-type integral 3D imaging using multi-facet flat mirrors

We propose a projection-type integral imaging scheme using multi-facet flat mirrors and demonstrate its feasibility. Instead of spherical mirrors on a flat surface, multi-facet flat mirrors which contacts with the tangential line of a curved surface function like elemental mirror component. Lights reflected from different facet of each mirrors give different viewing perspectives. By using electronic capturing and display devices, the proposed method makes it possible to record and reconstruct 3D scene in real-time. In the experiment, only horizontal parallax is provided because one-dimensional surface can be made more easily. But extension for two-dimensional or computer generation of elemental images can also be done.
