Implementation and characterization of the optical-see-through Maxwellian near-eye display prototype using three-dimensional printing

Journal of Information Display, 2020
By presenting always-in-focus virtual images, Maxwellian near-eye displays can remove the vergence accommodation conflict, which causes eye fatigue or dizziness.

Holographic Near-Eye 3D Display Method Based on Large-Size Hologram

Frontiers in Materials, 2021
In this paper, we propose a holographic near-eye 3D display method based on large-size computer-generated hologram (CGH). The reconstructed image with a large viewing angle is obtained by using a time multiplexing and spatial tiling system.

Wide-Field-of-View Near-Eye Display with Dual-Channel Waveguide

Photonics, 2021
We propose a wide-field-of-view near-eye display featuring a dual-channel waveguide with cholesteric liquid crystal gratings. Our dual-channel waveguide is capable of splitting the field of view through the orthogonal polarization division multiplexing ...

A perceptual eyebox for near-eye displays

Optics Express, 2020
In near-eye display systems that support three-dimensional (3D) augmented and virtual reality, a central factor in determining the user experience is the size of the eyebox. The eyebox refers to a volume where the eye receives an acceptable view of the image with respect to a set of criteria and thresholds.

Large Depth of Range Maxwellian-Viewing SMV Near-Eye Display Based on a Pancharatnam-Berry Optical Element

IEEE Photonics Journal, 2022
In order to overcome the accommodation and convergence (A-C) conflict that commonly causes visual fatigue in AR display, we propose a Maxwellian-viewing-super-multi-view (MV-SMV) near-eye display system based on a Pancharatnam-Berry optical element (PBOE)

Considerations of Curvature for a Near-Eye Holo-Video Display

Applied Sciences, 2020
Most 3D augmented reality, near-eye displays suffer from a low field of view. Leaky-mode lithium niobate devices are often used to steer, multiplex, or otherwise control the path of light in a system.

A Depth-Enhanced Holographic Super Multi-View Display Based on Depth Segmentation

Micromachines, 2023
A super multi-view (SMV) near-eye display (NED) effectively provides depth cues for three-dimensional (3D) display by projecting multiple viewpoint or parallax images onto the retina simultaneously.
