Wide-viewing-angle three-dimensional integral imaging using a curved screen and a curved lens array

Abstract

In this paper, we propose a wide-viewing-angle three-dimensional integral imaging using a curved screen and a curved lens array. Elemental images are projected to the curved screen. Incorporation of the curved screen and the curved lens array instead of a conventional flat display panel and a flat lens array expands the viewing angle remarkably. In addition adopting barriers between a curved lens array and a curved screen eliminates the flipped images effectively without affecting the viewing angle. The principle of the proposed system is explained and the experimental results about the viewing angle of real and virtual images are also presented.
