High Space‐Bandwidth‐Product (SBP) Hologram Carriers Toward Photorealistic 3D Holography

Laser &Photonics Reviews, Volume 18, Issue 7, July 2024.
In a classic hologram device, the hologram carrier directly determines the display capability and the design of the high space‐bandwidth‐product (SBP) of optical systems. Here, a fundamental progress report of the main hologram carriers (SLM and metasurface), which are widely utilized in holographic displays and holography systems to achieve high SBP ...

High-Resolution Hogel Image Generation Using GPU Acceleration

Photonics
A holographic stereogram displays reconstructed 3D images by rearranging multiple 2D viewpoint images into small holographic pixels (hogels). However, conventional CPU-based hogel generation processes these images sequentially, causing computation times ...

Comparative Evaluation of 2D and 3D Gaussian Splatting for Full-Parallax Holographic Stereogram Printing

Applied Sciences
Holographic stereograms record large sets of multi-view projection images into elementary hologram units (hogels), and their visual quality is governed primarily by the quality and inter-view consistency of the input multi-view imagery.

Transforming Monochromatic Images into 3D Holographic Stereograms Through Depth-Map Extraction

Applied Sciences
Traditional holographic printing techniques prove inadequate when only input data are available. Therefore, this paper proposes a new artificial-intelligence-based process for generating digital holographic stereograms from a single black-and-white ...

Aspects of Holographic Superconductivity [PDF]

, 2012
In this thesis we study two different aspects of holographic superconductivity. First we study fully backreacting Gauss-Bonnet (GB) holographic superconductors in 5 bulk spacetime dimensions. We explore the system’s dependence on the scalar mass for both

Comparison of holographic photopolymer materials by use of analytic nonlocal diffusion models [PDF]

, 2002
The one-dimensional diffusion equation governing holographic grating formation in photopolymers, which includes both nonlocal material response and generalized dependence of the rate of polymerization on the illuminating intensity, has been previously ...

Holographic multi-stereogram constructed from computer images : Applied 3-D printer [PDF]

, 1996
The aim of this thesis is to develop a method to convert computer images to a holographic film plate. In the recording process of holographic multi-stereograms, one uses a liquid crystal display (LCD) to show 70 different pictures of a constructed object.
