Stereogram implemented with a holographic image splitter

Optics Express, 2011
A special holographic optical element (HOE) which is used as an image splitter is developed to generate a stereogram on a 2.2-in. liquid crystal display panel. The special designed holographic optical element can be attached on the conventional panel directly to replace the traditional image splitter in a stereoscopic display panel.

126 COLOR HOLOGRAPHIC STEREOGRAM

Journal of the Visualization Society of Japan, 1995
Using the rainbow holographic technique, a color or an achromatic image can be obtained from the superposition of various rainbow holograms on a single plate. Since the color of the reconstructed image depends on the observation angle, the desired image is obtained at a specific viewing position. Using Kogelnik's theory an analysis of the image's color

Incoherent Digital Holography Empowered by Wavefront and Information Engineering: A Review

Advanced Photonics Research, Volume 6, Issue 10, October 2025.
Advancements in incoherent digital holography (IDH) have been achieved via wavefront engineering (using spatial light modulators, diffractive optics, and metasurfaces) and information engineering (using compressive sensing and deep learning). This paper presents an overview of IDH with wavefront and information engineering, paving the way toward its ...

Real‐Time Rendering Framework for Holography

Computer Graphics Forum, Volume 44, Issue 2, May 2025.
Abstract With the advent of holographic near‐eye displays, the need for rendering algorithms that output holograms instead of color images emerged. These holograms usually encode phase maps that alter the phase of coherent light sources such that images result from diffraction effects.

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 ...

Interactive holographic stereograms with accommodation cues [PDF]

SPIE Proceedings, 2010
Image-based holographic stereogram rendering methods for holographic video have the attractive properties of moderate computational cost and correct handling of occlusions and translucent objects. These methods are also subject to the criticism that (like other stereograms) they do not present accommodation cues consistent with vergence cues and thus
