Abstract
A new integral-imaging-based light field augmented-reality display is proposed and implemented for the first time, to our best knowledge, to achieve a wide see-through view and high image quality over a large depth range. By using custom-designed freeform optics and incorporating a tunable lens and an aperture array, we demonstrated a compact design of a light field head-mounted-display that offers a true 3D display view of 30° by 18°, maintains a spatial resolution of 3 arc minutes across a depth range of over 3 diopters, and provides a see-through field of view of 65° by 40°.
Highlights
Conventional stereoscopic displays, which present a pair of stereoscopic images with binocular disparities and other pictorial depth cues on a fixed image plane to stimulate the perception of 3D space and shapes, lack the ability to correctly render focus cues, including accommodation and retinal blur effects

Summary
Conventional stereoscopic displays, which present a pair of stereoscopic images with binocular disparities and other pictorial depth cues on a fixed image plane to stimulate the perception of 3D space and shapes, lack the ability to correctly render focus cues, including accommodation and retinal blur effects. We focus on developing new optical solutions that help to overcome the above-mentioned limitations of the state-of-the-art 3D light field displays based on integral imaging method and significantly improve the overall optical performance of this type of 3D displays To achieve this goal, we propose a new optical architecture for a high-performance InI-based light field OST-HMD system, consisting of three key sub-units, a micro-InI unit integrated with a custom aspherical MLA and a custom aperture array, a tunable relay group that is able to dynamically tune the axial position of the reconstructed light field of a 3D miniature scene, and a custom freeform eyepiece (Sec. 2). There is no prior art that has ever demonstrated a true 3D AR display using integral imaging with comparable optical performance and form factor
