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.

A new method of digital holographic 3D-display

2015 IEEE 13th International Conference on Industrial Informatics (INDIN), 2015
A new method for reconstructing whole optical wave fields with correct intensity and phase is presented which is based on the interference of two mutually coherent phase fields modulated by two spatial light modulators of the liquid crystal on silicon type.

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.

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.

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.

Replication optics for a holographic 3D display system

SPIE Proceedings, 2003
The display of 3D images containing all the depth cues required by the human vision system can be achieved using a reconfigurable Computer Generated Hologram (CGH) with high pixel count. A technique which has been developed to produce CGH's with the required number of pixels, and at video refresh rates, is known as Active Tiling TM (AT).

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).

Future of photorefractive based holographic 3D display

SPIE Proceedings, 2010
The very first demonstration of our refreshable holographic display based on photorefractive polymer was published in Nature early 2008 1 . Based on the unique properties of a new organic photorefractive material and the holographic stereography technique, this display addressed a gap between large static holograms printed in permanent media ...

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 ...
