A scheme for the resolution-enhancement of a three-dimension/two-dimension convertible display based on integral imaging is proposed. The proposed method uses an additional lens array, located between the conventional lens array and a collimating lens. Using the additional lens array, the number of the point light sources is increased far beyond the number of the elemental lenses constituting the lens array, and, consequently, the resolution of the generated 3D image is enhanced. The principle of the proposed method is described and verified experimentally.

    • "Although the size of the elemental lens is small, the spatial resolution of PLS display increases, but it reduces an angular resolution due to reduced number of SLM pixels corresponding to each elemental lens. From Figure 2, 3D integrated point appears in the cross section of diverged rays from the PLSs so a viewing angle of PLS display is determined by diverging angle of the PLS [12]. That is given by "

    ABSTRACT: ABSTRACT In this paper, a three-dimensional (3-D) integral imaging (II) system to improve the viewing angle by using the multiple illuminations is proposed. In this system, three collimated illuminations that are directed to three different angles in order to get widen propagation angle of point light source (PLS). Among three illuminations two slanted illuminations increase the propagation angle of PLS over the conventional method. Simulation result shows that the viewing angle of proposed PLS displays is three times larger than conventional PLS displays. In the simulation, we used Light Tools 6.3 to reconstruct an object.

    ABSTRACT: Integral imaging is one of the most feasible directional displays that give different perspectives according to viewing directions. It has inborn characteristics such as viewing angle, resolution, and depth range because of lens array or pinhole array. In this paper, recent integral imaging techniques for improving these features in display are reviewed. New approaches such as integral floating display and two-dimensional three-dimensional (2D/3D) convertible integral imaging method are described as well.

    ABSTRACT: A wide-viewing-angle 3D/2D convertible display system with a thin structure is proposed that is able to display three-dimensional and two-dimensional images. With the use of a transparent display device in front of a conventional integral imaging system, it is possible to display planar images using the conventional system as a backlight source. By experiments, the proposed method is proven and compared with the conventional one.
