Viewing angle-enhanced integral imaging system using three lens arrays

We propose an integral imaging system that uses three lens arrays, including two convex lens arrays and a concave lens array. Compared with the conventional integral imaging system, the proposed system can remarkably enhance the viewing angle. The maximum viewing angle can be enlarged to 48 , which is 4.8 times wider than that of the conventional system. The principle of the proposed system is elucidated, and the experimental results are presented in this letter.
