3D displays: toward holographic video displays of 3D images

Chinese Optics Letters, 2013
As the flat panel displays (Liquid Crystal Displays, AMOLED, etc.) reach near perfection in their viewing qualities and display areas, it is natural to seek the next level of displays, including 3D displays. There is a strong surge in 3D liquid crystal displays as a result of the successful movie Avatar. Most of these 3D displays involve the employment

Holographic 3D Touch Sensing Display

Digital Holography & 3-D Imaging Meeting, 2015
A 3D image floating in the air is reproduced by a 3D light-field display using a holographic screen, and a 3D touch interface is implemented by detecting the touch to the reproduced real image.

Real time 3D holographic display

SPIE Proceedings, 2012
In this article is described a Real Time 3D video display of holographic images based on the principle of sequential scanning of holograms with HPO (horizontal parallax only) generated by a high speed computer and sent at high frame rate to DMD, and visualized by an anamorphic optical group.

Advances in interactive, holographic 3D displays

The 15th Annual Meeting of the IEEE Lasers and Electro-Optics Society, 2003
Reconfigurable computer generated holography - sometimes known as electroholography - is the only technique capable of using computer held data to generate interactive, high quality, 3D images containing all the depth cues used by the human visual system.

Curved multiplexing method for 3D holographic display

Imaging and Applied Optics Congress, 2020
A curved multiplexing method is proposed to increase the view angle and information capacity. The different objects are reconstructed by bending a composite hologram. It is proven to be viable theoretically and experimentally.

Super-fast refresh holographic liquid crystals for holographic 3D display

SPIE Proceedings, 2015
Doped liquid crystals, as super-fast refresh holographic media, are very useful in holographic 3D video display because of their extraordinarily high optical nonlinearity arising from laser-induced director axis reorientation. We obtained real-time dynamic holographic display with holographic response time under an order of a microsecond using the ...

Multi-illumination 3D holographic display using a binary mask

Optics Letters, 2022
We introduce a novel, to the best of our knowledge, method to increase the bandwidth in holographic displays. Here, multi-angle illumination using multiple laser diodes (LDs) is adopted to expand the limited diffraction angle of the spatial light modulator (SLM).

A 3D acquisition method for holographic display

SPIE Proceedings, 2014
It is well known that holographic display can provide 3D scenes with continuous viewpoints and is free of accommodation-convergence conflict. So far most of the research in this area focuses on the display end, leaving the acquisition end merely explored. For holographic content acquisition, one needs to capture the scene in 3D. Ways to do this include

A low-resolution 3D holographic volumetric display

SPIE Proceedings, 2010
A simple low resolution volumetric display is presented, based on holographic volume-segments. The display system comprises a proprietary holographic screen, laser projector, associated optics plus a control unit. The holographic screen resembles a sheet of frosted glass about A4 in size (20x30cm).

An Updatable Holographic Display for 3D Visualization

Journal of Display Technology, 2008
Among the various methods to produce three-dimensional (3D) images, holography occupies a special niche. Indeed, holograms provide highly realistic 3D images with a large viewing angle capability without the need for special eyewear. Such characteristics make them valuable tools for a wide range of applications such as medical, industrial, military ...
