Abstract

A scheme of quarter-overlapped microlens arrays (QOMLA) is proposed to improve the display performance of integral imaging (II). The theory and the design of QOMLA is presented by the combination of geometric optics and wave optics and is verified by the optical experiments. The angular sampling density of the II system can be doubled in each dimension to further increase the spatial resolution. Multiple central depth planes can be constructed by adjusting the spacing of the multilayers, so as to expand the depth of field (DoF). Furthermore, QOMLA is easier to process when compared with the single-layer microlens array, and it reduces processing costs.
