Three-dimensional projection integral imaging using micro-convex-mirror arrays

Three-dimensional projection integral imaging using micro-convex-mirror arrays is presented. In this scheme, a pseudoscopic to orthoscopic image conversion process is not required even if elemental images of direct camera pickup are used. In addition, a wide viewing angle without image flipping can be achieved even if optical barriers are not used. The feasibility of the proposed scheme was experimentally demonstrated, in which the viewing angle of more than 60 degrees was obtained. To the best of our knowledge, this is the largest viewing angle demonstrated by a single integral imaging system. (C) 2004 Optical Society of America.
