Enhanced performance integral imaging 3D display method using quarter-overlapped microlens arrays

Abstract

An integral (II) imaging method using quarter-overlapped microlens arrays (QOMLA) is proposed to improve the display performance. The principle and the simulation of POMLA is analyzed by geometric optics and wave optics, and the optical experiments verify the enhancement of performance. POMLA can double the angular sampling density of II systems in each dimension to increase the spatial resolution, and is able to construct multiple central depth planes by adjusting the gap between the two layers to expand the depth of field. Moreover, POMLA is easier to be processed compared with the same lenslets size single-layer microlens array and reduces the processing cost.
