Paper Abstract

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 switching to improve the viewing angle of integral imaging. In this paper, we propose a viewing angle enhanced integral imaging system without any mechanical movement or polarization control. This new viewing angle enhanced system utilizes lenticular lens sheet to angularly multiplex the information emitted from each pixel. Thus each pixel can affect multiple lenses and the effective area of an elemental image is increased, which brings the enhanced viewing angle. The simulation result of the proposed system and the experimental results are provided.
