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 ...

3D Image Display Using Holographic Stereograms

SPIE Proceedings, 1989
The holographic stereogram is synthesized from a series of ordinary photographs, and is a very attractive medium for displaying 3D images. This paper presents a method of synthesizing a cylindrical hologrphic stereogram with white light reconstruction called multiplex hologram, and fundamental properties of reconstructed images such as distortion and ...

Holographic Display of 3D Data

1992
Holography is a powerful optical technique for recording and displaying 3D information. In this chapter we discuss the application of holography in the display of tomographic data. It helps to have a good understanding of 3D perception in order to determine whether holography can be used beneficially in the display of scientific and medical data.

Materials for an Updatable Holographic 3D Display

Journal of Display Technology, 2010
Holography is a powerful technique for providing high-resolution, realistic three-dimensional (3D) images without the need for special eyewear. A material that takes full advantage of the potential of holography, including updatability, has not existed.

21-inch color 3D dynamic holographic display

Digital Holography and Three-Dimensional Imaging 2019, 2019
A compact display system is proposed for color dynamic holographic display with a 21-inch liquid crystal display (LCD) panel. An independent block holographic algorithm is developed to record accurate depth information.
