3D touchable holographic light-field display
Applied Optics, 2016We 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

Rendering for an interactive 360° light field display [PDF]
ACM Transactions on Graphics, 2007 Figure 1: A 3D object shown on the display is photographed by two stereo cameras (seen in the middle image). The two stereo viewpoints sample the 360 ◦ field of view around the display.

Glasses-free light field 3D display
2015 Visual Communications and Image Processing (VCIP), 2015This 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,

Slit-based light field 3D display
ACM SIGGRAPH 2014 Emerging Technologies, 2014The 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.

Compression for full-parallax light field displays
SPIE Proceedings, 2014Full-parallax light field displays utilize a large volume of data and demand efficient real-time compression algorithms to be viable. Many compression techniques have been proposed. However, such solutions are impractical in bandwidth, processing or power requirements for a real-time implementation.

Perceptually-guided foveation for light field displays
ACM Transactions on Graphics, 2017A variety of applications such as virtual reality and immersive cinema require high image quality, low rendering latency, and consistent depth cues. 4D light field displays support focus accommodation, but are more costly to render than 2D images, resulting in higher latency.

Fast rendering and display of light field images with a controllable lighting mechanism
Optics Letters, 2022A fast light field (LF) image rendering method with controllable lighting mechanism is proposed and demonstrated. It solves the issue that previous image-based methods could not render and edit lighting effects for LF images. In contrast to previous methods, light cones and normal maps are defined and used to expand the RGBD images into RGBDNθ data ...

Dual-layered light field display
ACM SIGGRAPH 2017 Posters, 2017In this work, we propose a novel light field approximation method for multi-layer light field display. Our target light field display consists of two liquid crystal panels with a uniform back-light with no time multiplexing. LCD panels are not necessarily to be parallel.

Holographic Display of Digital Light Field
Digital Holography and Three-Dimensional Imaging, 2016Four historical important stages in display holography have been described in detail. While the first three is hard to achieve dynamic optical field display, the holographic display of digital light field by means of the holographic functional screen(HFS) could be thought as the fourth to bring up holographic video without the redundant hologram itself.

Display-specific light-field analysis
SPIE Proceedings, 2014Present generations of 3D displays including stereoscopic and autostereoscopic displays have very limited number of views, and thus limited parallax. In contrast, the emerging light field (LF) displays support hundred(s) of views with acceptable spatial resolution thereby enabling a more realistic representation of 3D scenes.
