Abstract

This paper proposes a practical method to analyze the expressible depth range of an integral imaging system based on image blur at defocused depths, which is one of the most noticeable image degradations, caused by overlaps among voxels in both the real and focused mode. In order to obtain the preferably precise area of overlaps among voxels at each depth, display pixels are regarded as surface light sources in the process of voxel size calculation. As a criterion for determining the range, we determine the tolerable limit of the overlaps among voxels to be at least resolved from each other. Based on this principle, several mathematical expressions about the expressible depth range can be derived in both the real mode and focused mode, and their feasibilities are demonstrated by several experiments. The analyses are processed based on both wave optics and ray optics.
