Systematic characterization and optimization of 3D light field displays

Optics Express, 2017
One of the key issues in conventional stereoscopic displays is the well-known vergence-accommodation conflict problem due to the lack of the ability to render correct focus cues for 3D scenes.

Effects of ray position sampling on the visual responses of 3D light field displays

Optics Express, 2019
A 3D light field display typically reconstructs a 3D scene by sampling either the projections of the 3D scene at different depths or the directions of the light rays apparently emitted by the 3D scene and viewed from different eye positions.

3D touchable holographic light-field display

Applied Optics, 2016
We propose a new type of 3D user interface: interaction with a light field reproduced by a 3D display. The 3D display used in this work reproduces a 3D light field, and a real image can be reproduced in midair between the display and the user. When using a finger to touch the real image, the light field from the display will scatter. Then, the 3D touch

Slit-based light field 3D display

ACM SIGGRAPH 2014 Emerging Technologies, 2014
The principle of glasses-free 3D displays (each eye sees a different image without wearing glasses) can create a fully natural sensation of depth. In conventional principles, lenticular lenses or parallax barriers are placed in front of an image source, such as a liquid crystal display, to allow it to show a stereoscopic image.

Glasses-free light field 3D display

2015 Visual Communications and Image Processing (VCIP), 2015
This paper presents a demo system that realistically displays the glasses-free light field 3D effect with a triple-layer structure. By combining multi-layer panels, high refresh rates, and directional backlighting together, we achieve a wide field of view and large depth of field with a thin form factor. Additionally, using some off-the-shelf hardware,

Rank analysis of a light field for dual-layer 3D displays

2015 IEEE International Conference on Image Processing (ICIP), 2015
In this paper, a new type of 3D display, called a layered light-field display, was investigated. By using only a few light-attenuating layers located in front of a backlight, this display can present many views in different directions simultaneously without sacrificing the resolutions of each view.

Depth reconstruction for 3D light-field display based on axially distributed light field

Optical Engineering, 2021
Continuous depth maps are reconstructed based on depth estimation from light-field data of axially distributed image sensing (ADS). In the proposed method, the light field of ADS is introduced, and the light-field trajectory function is presented, which formulates the relationship between image point positions in different axially captured images and ...
