چکیده
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.

Viewing-angle-enhanced three-dimensional integral imaging using the combination of a lenticular lens sheet and a two-dimensional lens array [5642-55]
Integral imaging is a promising way of three-dimensional display because it provides observers with full parallax and continuous view points without the use of glasses. However, the limitation on the viewing angle and the expressible depth should be overcome for integral imaging to be applied to real systems. There have been various methods such as using mechanical movements or polarization swi...
متن کاملWide-viewing integral imaging system using polarizers and light barriers array
Background: Integral imaging is considered one of the most promising three-dimensional display technologies, while the limited viewing angle is regarded as a primary disadvantage of integral imaging display to reach a commercial level. This paper proposes a viewing angle enhancement method for both liquid crystal display (LCD) and the projection-type three-dimensional integral imaging system. M...
متن کاملThe use of a negative index planoconcave lens array for wide-viewing angle integral imaging.
Wide-viewing angle integral imaging by means of a negative refractive index planoconcave lens array is theoretically investigated. The optical properties of a negative refractive index lens are analyzed from the point of view of integral imaging. The effective focal length of a positive index planoconvex lens and a negative index planoconcave lens with the same surface spherical curvature R are...
متن کاملIntegral imaging system using an electroluminescent film backlight for three-dimensional-two-dimensional convertibility and a curved structure.
We propose a thin and compact integral imaging system using electroluminescent (EL) films as backlight. EL film has the advantage that it can operate continuously even when it is cut or punctured. Using this characteristic, we generate an array of pinholes on EL film to form a point light-source array for reconstructing three-dimensional (3D) images based on integral imaging. The EL pinhole fil...
متن کاملWide viewing angle dynamic holographic stereogram with a curved array of spatial light modulators.
A novel design of dynamic holographic stereogram with a curved array of spatial light modulators (SLMs) is proposed. In general, it is difficult to simultaneously achieve a wide viewing angle and an available width for the digital holographic display. Moreover, the wide viewing angle of a display system needs a large optical numerical aperture where the paraxial approximation fails, and thus an...
