Integral 3D imaging that has an enhanced viewing angle along full directions with no mechanical movement

The integral 3D imaging provides full motion parallax unlike other conventional stereoscopy-based techniques. To make most of this advantage, a 3D system that has a wide view along full direction is required. In this paper, we propose and demonstrate a method to enhance the viewing angle in integral imaging along both horizontal and vertical direction. Proposed system consists of two sub systems that have properly designed polarizing masks. The viewing angle enhancement along full direction is achieved by elemental lens switching that combines time and spatial multiplexing of different elemental image arrays. Some experimental results and the method to avoid a cross-talk effect are shown and discussed.
