Paper Abstract

Integral imaging is known as a promising 3D display method for its ability to reconstruct the light field of the scene. However, integral imaging suffers from low spatial resolution and narrow viewing angle due to the limited spatial bandwidth product of LCD, which prevents its commercial application. In conventional integral imaging display, spatial resolution and viewing angle are two vital factors that should be considered, and many previous research focuses on the two factors. A novel integral imaging 3D display system with large viewing angle about 35° and high spatial resolution for HVS is presented. The method is composed of a high definition 5K LCD panel, a macro lens array and a light shaping diffusor. One point of the method different from conventional integral imaging in which micro lens array is used, a macro lens array with elemental lens diameter 1cm is employed in our method to ensure a large viewing angle, however, this may result in low spatial resolution for HVS. And the other point is a light shaping diffusor is placed in front of the lens array with proper distance, and lifelike 3D reconstruction is obtained. Experimental results with full parallax, large viewing angle and high resolution 3D images are shown to verify the validity of the proposed system.
