The artistic use of parallax and lenses revealing the invisible in holography [PDF]

open access: yes, 2012
There are many artistic resources offered by holography: third-dimension registration and reconstruction, immateriality, color interpretation, holographic space, realism, etc.

Special Issue on Digital Holographic 3D Imaging: Capture, Display, and Evaluation

open access: yesETRI Journal, 2019
Holography has been fascinating people for almost 70 years (since Gabor's invention in 1947) as a true three‐dimensional (3D) imaging technology that can replicate 3D scenes in free space.

Dynamic Holographic Display Based on Perovskite Nanocrystal Doped Liquid Crystal Film

open access: yesIEEE Photonics Journal, 2021
Holography can produce the most real three-dimensional (3D) image, and is considered as the ultimate 3D display technology. However, compared with other display technologies, it has not been practically available in video display so far due to low ...

Super-Fast Refresh Holographic Display Based on Liquid Crystal Films Doped With Silver Nanoparticles

open access: yesIEEE Photonics Journal, 2019
Holography as a true three-dimensional (3-D) technique is thought to be the ultimate display technique. However, dynamic holographic materials still have problems such as slow refresh, high applied electrical field, etc., to be solved to realize video ...

Optimal Spatial Coherence of a Light-Emitting Diode in a Digital Holographic Display

open access: yesApplied Sciences, 2022
The coherence of a light source is a vital aspect regarding the image quality of holographic contents. Generally, the coherence of the light source is the reason for speckle noise in a holographic display, which degrades the image quality.

Electronic Tabletop Holographic Display: Design, Implementation, and Evaluation

open access: yesApplied Sciences, 2019
Most of the previously-tried prototype systems of digital holographic display are of front viewing flat panel-type systems having narrow viewing angle, which do not meet expectations towards holographic displays having more volumetric and realistic 3 ...

Short-time Fourier transform laser Doppler holography [PDF]

open access: yes, 2013
We report a demonstration of laser Doppler holography at a sustained acquisition rate of 250 Hz on a 1 Megapixel complementary metal-oxide-semiconductor (CMOS) sensor array and image display at 10 Hz frame rate.

Metasurface-Based Holographic Display With All-Dielectric Meta-Axilens

open access: yesIEEE Photonics Journal, 2021
In a classical metasurface-based holographic display system, a clear holographic reconstruction image can be obtained only in the back-focal-plane of the lens. However, when the receiving plane deviates from the focal plane, the reconstructed holographic

A Fast Computer-Generated Holographic Method for VR and AR Near-Eye 3D Display

open access: yesApplied Sciences, 2019
A fast computer-generated holographic method with multiple projection images for a near-eye VR (Virtual Reality) and AR (Augmented Reality) 3D display is proposed.
