An Integral-imaging-based Head Mounted Light Field Display Using a Tunable Lens and Aperture Array

A head-mounted light field display based on integral imaging is considered as one of the promising methods that can render correct or nearly correct focus cues and address the wellknown vergence-accommodation conflict problem in head mounted displays. Despite its great potential, it still suffers some of the same limitations of conventional integral imaging based displays such as low spatial resolution and crosstalk. In this paper, we present a prototype design using tunable lens and aperture array to render 3D scenes over a large depth range while maintaining high image quality and minimizing crosstalk. Experimental results verify and show that the proposed design could significantly improve the viewing experience.
