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 well-known 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.
