Fast 3D Content Update for Wide-Angle Holographic Near-Eye Display
Applied Sciences, 2021 Near-eye holographic displays are the holy grail of wear-on 3D display devices because they are intended to project realistic wide-angle virtual scenes with parameters matching human vision.

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.

Eyebox expansion with accurate hologram generation for wide-angle holographic near-eye display.
Optics Express, 2023 Small eyebox in wide-angle holographic near-eye display is a severe limitation for 3D visual immersion of the device. In this paper, an opto-numerical solution for extending the eyebox size in these types of devices is presented. The hardware part of our

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 ...

Binocular full-color holographic three-dimensional near eye display using a single SLM.
Optics Express, 2023 A binocular full-color holographic three-dimensional near eye display system using a single spatial light modulator (SLM) is proposed. In the display system, the frequency spectrum shifting operation and color spectrum shifting operation are adopted to ...

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

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.
