Sparse holographic imaging for an integrated augmented reality near-eye display.

Applied Optics, 2023
Diffraction is the main physical effect involved in the imaging process of holographic displays. In the application of near-eye displays, it generates physical limits that constrain the field of view of the devices.

Manufacturing Application-Driven Foveated Near-Eye Displays

IEEE Transactions on Visualization and Computer Graphics, 2019
Traditional optical manufacturing poses a great challenge to near-eye display designers due to large lead times in the order of multiple weeks, limiting the abilities of optical designers to iterate fast and explore beyond conventional designs. We present a complete near-eye display manufacturing pipeline with a day lead time using commodity hardware ...

High dynamic range near-eye displays

Optical Architectures for Displays and Sensing in Augmented, Virtual, and Mixed Reality (AR, VR, MR), 2020
The sensitivity of the human visual system to brightness and contrast is orders of magnitude higher than what current neareye displays can emulate. Although high brightness and contrast, which in combination is defined as high dynamic range (HDR) in this work, are critical to the realism provided by near-eye displays, these parameters are often ...

Phase-only color rainbow holographic near-eye display

Optics Letters, 2021
Color rainbow holography can realize color holographic 3D display without speckle noise under white light illumination. However, traditional color rainbow holograms used for high-resolution static color 3D display or near-eye color display are amplitude-type, resulting in low diffraction efficiency due to the presence of conjugate light. In this Letter,

Compact Monocular 3D Near-eye Display

Imaging and Applied Optics 2017 (3D, AIO, COSI, IS, MATH, pcAOP), 2017
Compact monocular 3D near-eye displays are proposed by using holographic waveguide combiner to reduce the weight and volume of its optical parts. The complex amplitude modulation technique is introduced to the system to solve the accommodation-convergence conflict of human eyes.

Holographic optical elements for head-up displays and near-eye displays

Advances in Display Technologies XI, 2021
Various technologies to realize the augmented reality (AR) devices have been proposed. Holographic optical element (HOE) is among the most appealing optical components for the optical combiner of AR devices. With the compact size and bendable material, HOE can be applied to AR systems with various form factors.

Steerable application-adaptive near eye displays

ACM SIGGRAPH 2018 Emerging Technologies, 2018
The design challenges of see-through near-eye displays can be mitigated by specializing an augmented reality device for a particular application. We present a novel optical design for augmented reality near-eye displays exploiting 3D stereolithography printing techniques to achieve similar characteristics to progressive prescription binoculars.

Design of a dual focal-plane near-eye display using diffractive waveguides and multiple lenses.

Applied Optics, 2022
We propose a method to construct a compact dual focal-plane optical see-through near-eye display using diffractive waveguides and multiple lenses. A virtual image from a display device is projected into a three-grating waveguide using an objective lens ...
