Integral Imaging Tabletop 3d Display System

We propose an integral imaging tabletop three-dimensional (3D) display system. The system uses a dynamic tilted barrier array combined with a high-brightness two-dimensional display panel and lens array to provide tabletop 3D images with a complete 360 degrees viewing zone. Besides, we propose a high-efficient elemental image array (EIA) generation method based on the backward ray-tracing technique for the integral imaging tabletop 3D display system. The EIA can be obtained in one rendering step by calculating the backward rays from all viewpoints to the corresponding pixels of the EIA. The experimental results verify the feasibility of the integral imaging tabletop 3D display system and the high-efficient EIA generation method.
