A simulator for a light field display
SPIE Proceedings, 2017A simulator which can test the visual perception response of light field displays is introduced. The simulator can provide up to 8 view images to each eye simultaneously to test the differences between different numbers of different view images in supermultiview condition.

Advances in Display Technologies VIII, 2018
In this paper, a new type of light field display by combining additive and multiplicative light field displays is proposed. Combination of the two types of compressive light field displays makes the system compact, improves the light efficiency, and alleviates the diffraction effect.

Light-Field Displays: a View-Dependent Approach
ACM SIGGRAPH 2020 Emerging Technologies, 2020Most 3D displays suffer from the vergence-accommodation conflict, which is a significant contributor to eyestrain. Light-field displays avoid this conflict by directly supporting accommodation but they are viewed as requiring too much resolution to be practical, due to the tradeoff between spatial and angular resolution.

Multi-layer light field display characterisation
2016 3DTV-Conference: The True Vision - Capture, Transmission and Display of 3D Video (3DTV-CON), 2016Light field 3D displays, where a hologram-like image is produced by using geometrical optical techniques as opposed to interference of light, require different measurement procedures to conventional stereoscopic displays for the measurement of certain parameters.

Ray tracing for HoloVizio light field displays
2017 International Conference on 3D Immersion (IC3D), 2017Ray tracing is a well-known method of virtual 3D scene visualization. Nowadays it is mostly used for the rendering of photo-realistic static pictures for conventional 2D displays. In this paper, we describe the implementation of a ray tracing algorithm for a specific type of 3D rendering system, namely for the HoloVizio horizontally parallax light ...

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.
