Wide-Viewing-Angle Integral Imaging System with Full-Effective-Pixels Elemental Image Array

open access: yesMicromachines, 2023
There exists a defect of the narrow viewing angle in the conventional integral imaging system. One reason for this is that only partial pixels of each elemental image contribute to the viewing angle and the others cause image flips. In this paper, a wide-

Large viewing angle holographic 3D display system based on maximum diffraction modulation

open access: yesLight: Advanced Manufacturing, 2023
An ideal holographic 3D display should have the characteristics of large viewing angle, full color, and low speckle noise. However, the viewing angle of the holographic 3D display is usually limited by existing strategies, which vastly hinders its ...

Dual-View Integral Imaging System With Wide Viewing Angle And High Spatial Resolution

open access: yesIEEE Photonics Journal, 2020
In this paper, a dual-view integral imaging system is proposed to present two different 3D images for viewers in different viewing zones. For most of the conventional dual-view integral imaging systems, either the viewing angle or the spatial resolution ...

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

open access: yesFrontiers 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.

Angling for A Better View [PDF]

open access: yesBiophysical Journal, 2016
Viewing long-standing questions and challenges through a different lens can often provide unique insights and perspectives. This has been the key to many of the innovations emerging in the field of optical microscopy. Whether one is devising novel superresolution localization microscopies (1), new imaging reagents (2,3), or exploiting new imaging ...
