Geometrical holographic display

open access: yes, 2021
Is it possible to realize a holographic display with commercial available components and devices? Is it possible to manipulate light to reconstruct light field without using coherent light and complicated optical components? Is it possible to minimize the amount of date involved in building 3D scenes?

Video-rate laser Doppler vibrometry by heterodyne holography [PDF]

open access: yes, 2011
We report a demonstration video-rate heterodyne holography in off-axis configuration. Reconstruction and display of 1 Megapixel holograms is achieved at 24 frames per second, with a graphics processing unit.

Accurate Hologram Generation Using Layer-Based Method and Iterative Fourier Transform Algorithm

open access: yesIEEE Photonics Journal, 2017
Random phase is always added to the object to diffuse the object light in computer-generated holograms. However, this addition causes considerable speckle noise in the reconstructed image. For improving the speckle noise problem, we propose a new method,

Circular holographic video display system

open access: yesOptics Express, 2011
A circular holographic video display system reconstructs holographic video. Phase-only spatial light modulators are tiled in a circular configuration in order to increase the field of view. A beam-splitter is used to align the active area of the SLMs side by side without any gap. With the help of this configuration observers can see 3D ghost-like image

The Interactive Spatial Aesthetics between Holographic Display Technology and Dancing Body Language

open access: yesProceedings, 2022
The emergence of holographic stage art has made the concrete space of the dance theater fragmented, the virtuality and multiplicity place the dancers’ performances in a kind of phantom space beyond the object.

Universal scaling properties of extremal cohesive holographic phases [PDF]

open access: yes, 2014
We show that strongly-coupled, translation-invariant holographic IR phases at finite density can be classified according to the scaling behaviour of the metric, the electric potential and the electric flux introducing four critical exponents ...

Research trends in holographic 3DTV displays [PDF]

open access: yes2009 IEEE LEOS Annual Meeting Conference Proceedings, 2009
Holographic 3DTV and especially displays are attracting more attention. There are SLM based laboratory prototypes. Current images can be viewed from a very narrow angle. Satisfactory holographic displays can be expected within a decade.

A dynamic holographic modelling method of digital twin scenes for bridge construction

open access: yesInternational Journal of Digital Earth, 2023
Holographic projection technology can provide a more intuitive and efficient visualization effect for a digital twin bridge construction scene. However, pre-rendering methods in the existing research work are usually used to implement holographic ...

Noise and aliases in off-axis and phase-shifting holography [PDF]

open access: yes, 2008
We have compared the respective efficiencies of off-axis and phase-shifting holography in terms of noise and aliases removal. The comparison is made by analyzing holograms of an USAF target backlit with laser illumination, recorded with a charge-coupled ...
