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

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

Geometrical holographic display
, 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?

A floating type holographic display
Optics Express, 2013 A floating image type holographic display which projects an electronically generated holographic image together with a background image displayed on a monitor/TV to enhance the visual effects of the former image is introduced. This display can display a holographic image with a spatial volume floating in the front space of the display with use of PDLC ...

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

Holographic Geometry and Noise in Matrix Theory
, 2009 Using Matrix Theory as a concrete example of a fundamental holographic theory, we show that the emergent macroscopic spacetime displays a new macroscopic quantum structure, holographic geometry, and a new observable phenomenon, holographic noise, with ...

Circular holographic video display system
Optics 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
