Resolution Enhancement of Spherical Wave-Based Holographic Stereogram with Large Depth Range
Applied Sciences, 2021 The resolution-priority holographic stereogram uses spherical waves focusing on the central depth plane (CDP) to reconstruct 3D images. The image resolution near the CDP can be easily enhanced by modifying three parameters: the capturing depth, the pixel

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

Characteristic and optimization of the effective perspective images' segmentation and mosaicking (EPISM) based holographic stereogram: an optical transfer function approach. [PDF]
Sci Rep, 2018 Based on our proposed method for holographic stereogram printing using effective perspective images’ segmentation and mosaicking (EPISM), we analyze the reconstructed wavefront errors, and establish the exit pupil function model of proposed printing ...

Holostereosynthesis: An Improvement to Louis Lumière’s Photostereosynthesis Technique
Applied Sciences, 2022 In 1920, Louis Lumière, one of the fathers of Cinématograph, invented photostereosynthesis, a photography technique that could recreate three-dimensional images without a specific artifice.

Fast 3D Content Update for Wide-Angle Holographic Near-Eye Display
Applied Sciences, 2021 Near-eye holographic displays are the holy grail of wear-on 3D display devices because they are intended to project realistic wide-angle virtual scenes with parameters matching human vision.

Photonics, 2022 In near-eye displays (NEDs), issues such as weight, heat, and power consumption mean that the rendering and computing power is usually insufficient. Due to this limitation, algorithms need to be further improved for the rapid generation of holograms.

Digital Holographic Printing Methods for 3D Visualization of Cultural Heritage Artifacts
Digital Presentation and Preservation of Cultural and Scientific Heritage, 2014 Holography enables capture and reconstruction of the optical field scattered from three-dimensional (3D) objects. The hologram encodes both amplitude and phase of the field under coherent illumination, whereas photography records only the amplitude by ...

Studying the Recent Improvements in Holograms for Three‐Dimensional Display
International Journal of Optics, Volume 2014, Issue 1, 2014., 2014 Displayers tend to become three‐dimensional. The most advantage of holographic 3D displays is the possibility to observe 3D images without using glasses. The quality of created images by this method has surprised everyone. In this paper, the experimental steps of making a transmission hologram have been mentioned.

Computer generated 3D animated holographic stereograms [PDF]
, 1997 This thesis describes the process of creating and displaying a computer generated 3D animated holographic stereogram. The objective of the project was to create a computer generated 3-dimensional model and animate it to perform some action using an ...

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.
