Viewing-angle-enhanced display of large-depth 3D images in curved projection integral imaging

In this paper, we propose a curved projection integral imaging system having curvature effect by additional use of a large-aperture lens in conventional projection integral imaging system. The proposed system has simple structure due to the use of well-fabricated flat devices without any modification and can display 3D images simultaneously through real and virtual image fields. Using elemental images synthesized based on ABCD matrix, preliminary experiment are carried out and some experiment results are presented.
