Spatiotemporally multiplexed integral imaging projector for large-scale high-resolution three-dimensional display

Abstract

We present a projection method in integral imaging for large-scale high-resolution three-dimensional display. In the proposed method, the entire set of high resolution elemental images with a large number of pixels is spatially divided into smaller image subsets. Then they are projected separately onto the corresponding lenslet array positions either simultaneously or in a sequence faster than the flicker fusion frequency of human eyes or both (i.e., spatiotemporal multiplexing). Thus display panels that do not have enough pixel numbers can be used to display the entire elemental images with a large number of pixels. Preliminary experiments were performed using a galvanometer-based optical scanner.
