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,

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

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 ...

Measurement of perceived spatial resolution in 3D light-field displays

2014 IEEE International Conference on Image Processing (ICIP), 2014
Effective spatial resolution of projection-based 3D light-field (LF) displays is an important quantity, which is informative about the capabilities of the display to recreate views in space and is important for content creation. We propose a subjective experiment to measure the spatial resolution of LF displays and compare it to our objective ...
