Selective Couplers Based on Multiplexed Volume Holographic Gratings for Waveguide Displays

Photonics, 2021
Diffraction waveguides are widely used in augmented reality devices as information display systems for the introduction of data into the human visual field in order to supplement information about the world around us. This paper formulates the principles

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

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.

Lightguide type Maxwellian near-eye display with enlarged horizontal field of view by optical reconfiguration of input image

Journal of Information Display, 2022
We present a novel design of the lightguide type optical see-through Maxwellian near-eye display. The proposed display reconfigures vertically long input images to horizontally long output images for wide horizontal viewing-angle.

HoloBeam: Paper-Thin Near-Eye Displays

2023 IEEE Conference Virtual Reality and 3D User Interfaces (VR), 2023
An emerging alternative to conventional Augmented Reality (AR) glasses designs, Beaming displays promise slim AR glasses free from challenging design trade-offs, including battery-related limits or computational budget-related issues. These beaming displays remove active components such as batteries and electronics from AR glasses and move them to a ...

Guidelines for Pediatric Radiotherapy Simulation: A Report From the Children's Oncology Group Radiation Oncology Discipline

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric radiation therapy presents unique challenges compared to adult treatments, including those of immobilization, potential need for sedation, and the critical importance of accurate, reproducible positioning. Additionally, heightened attention to imaging doses is necessary to minimize long‐term toxicity in survivors.

Curved Holographic Augmented Reality Near-Eye Display System Based on Freeform Holographic Optical Element with Extended Field of View

Photonics
At present, most near-eye display devices adopt flat substrates, which have problems such as limited field of view (FOV) and bulky shape, while the curved structure is expected to expand the FOV with appropriate volume. In this paper, we propose a curved

Ironic Medications: A Narrative‐Based Psycho‐Educational Intervention to Explore Patient–Provider Communication in Adolescents With Haematological Cancer

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Adolescents with haematological malignancies face significant emotional and relational challenges, often accompanied by difficulties in communicating their needs within the healthcare context. To address these issues, a narrative‐based psycho‐educational intervention based on the creation and prescription of Ironic Medications was ...
