Abstract

In this paper, a novel three-dimensional (3-D) integral imaging system to simultaneously improve the depth-of-focus (DOF) and the resolution of the reconstructed object images by using the non-uniform lenslet array and the intermediate-view reconstruction technique (IVRT) is proposed. That is, by using the non-uniform lenslets, DOF-enhanced integral images of 3-D objects can be picked up, and then by applying the IVRT to these picked-up integral images, resolution as well as DOF-enhanced object images can be reconstructed. To show the feasibility of the proposed system, experiments with test objects are performed and the results are discussed.
