    Abstract

    In order to solve the problems of insufficient viewpoints and narrow viewing angle of the traditional autostereoscopic display technology, a light field three-dimensional (3D) display method with super multiple viewpoints and large viewing angle is proposed. Based on the principle of reconstructing full-parallax light field for integral imaging, the discrete lenticular lens array (DLLA) with a large pitch is used in the proposed method to horizontally modulate the light rays, which emit from pixels of the elemental image (EI), with specific horizontal direction angles to integrate viewpoints in space. As a result, super multiple viewpoints densely arranged in the horizontal direction are reconstructed within a large viewing angle. In addition, the DLLA is optimized for optical imaging to suppress aberrations and ensure high-quality 3D imaging. In the experiment, a 54-inch (1 inch=2.54 cm) light-emitting diode (LED) displayer with a resolution of 1280 pixel×720 pixel is used to achieve a horizontal light field 3D display effect with 42.8° viewing angle and 100 viewpoints, and the distortion rate of 3D imaging is 2.23%. The presented 3D image with continuous parallax of motion and natural expression of depth information verifies the superiority and feasibility of the proposed method.
