Demonstration of an improved integral imaging with large viewing angle based on two crossed lenticular lens combined arrays

An improved integral imaging with large viewing angle based on two crossed lenticular lens combined arrays (LLCAs) is demonstrated. The limitation of the viewing angle of the perceived three-dimensional (3D) scene constructed by the conventional integral imaging (InIm) is one of the most primary drawbacks of the conventional InIm for its commercial application. Here, the LLCA is designed and fabricated to enlarge the viewing angle, and the perceived 3D scene with large viewing angle produced by the proposed improved-InIm with two crossed LLCAs is presented. In the experiment, an improved InIm with 44° viewing angle based on two crossed LLCAs and the 23.6-inch liquid crystal display (LCD) panel with the resolution of 3840 × 2160 is realized, which can provide natural 3D visual effect with high quality.
