Foveated imaging for near-eye displays
Optics Express, 2018 The angular resolution of current near-eye display devices is still far below human-eye acuity. How to achieve retina-level resolution while keeping wide field-of-view (FOV) remains a great challenge. In this work, we demonstrate a multi-resolution foveated display with two display panels and an optical combiner. The first display panel provides a wide

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 ...

Maxwellian near-eye display with an expanded eyebox
Optics Express, 2020 Maxwellian view systems can be employed to circumvent the vergence-accommodation conflict in near-eye displays (NEDs), which directly project images onto the retina regardless of the human eye’s depth of focus. However, Maxwellian view optics typically have a limited eyebox, which prevents broader applications of this architecture in NEDs.

Probabilistic modeling of eye movement data during conjunction search via feature-based attention [PDF]
, 2007 Where the eyes fixate during search is not random; rather, gaze reflects the combination of information about the target and the visual input. It is not clear, however, what information about a target is used to bias the underlying neuronal responses. We

Foveated holographic near-eye 3D display
Optics Express, 2020 We present a foveated rendering method to accelerate the amplitude-only computer-generated hologram (AO-CGH) calculation in a holographic near-eye 3D display. For a given target image, we compute a high-resolution foveal region and a low-resolution peripheral region with dramatically reduced pixel numbers.

Geometric Lightguide for Near-eye Light Field Display
Optics Express, 2023 Most near-eye displays with one fixed focal plane suffer from the vergence–accommodation conflict and cause visual discomfort to users. In contrast, light field displays can provide natural and comfortable 3D visual sensation to users without the conflict.

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.

Creating effective focus cues in multi-plane 3D displays. [PDF]
, 2011 Focus cues are incorrect in conventional stereoscopic displays. This causes a dissociation of vergence and accommodation, which leads to visual fatigue and perceptual distortions.
