Abstract
Limited depth of field (DOF) and low lateral resolution are two main
shortages of conventional integral imaging for 3D display. In this paper,
we demonstrate an experimental approach to enhancing DOF of an integral imaging
system with coded elemental images captured by a cubic phase plate (CPP) coded
camera array. After digital process of the coded elemental images, we obtained
elemental images with enhanced DOF for 3D display. We employed the elemental
images to reconstruct a real 3D image in a 7 x 7 lens array integral imaging
system, indicating that proposed method can improve the depth of field and
lateral resolution of integral imaging system significantly.
