Holography, and the future of 3D display

open access: yesLight: Advanced Manufacturing, 2021
The pioneers of holography, Gabor, Leith, Upatnieks, and Denisyuk, predicted very early that the ultimate 3D display will be based on this technique. This conviction was rooted on the fact that holography is the only approach that can render all optical ...

An Augmented-Reality Holographic Stereogram Based on 3D Optical Field Information Manipulation and Reconstruction

open access: yesFrontiers in Physics, 2022
Holographic stereogram comprises a hotspot in the field of three-dimensional (3D) display. It can reconstruct the light field information of real and virtual scenes at the same time, further improving the comprehensibility of the scene and achieving the “

Digital Holographic Printing Methods for 3D Visualization of Cultural Heritage Artifacts

open access: yesDigital 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 ...

Enlargements of Viewing Zone and Screen Size of Holographic Displays Using MEMS SLM Combined with Scanning Systems

open access: yesApplied Sciences, 2022
The problems of conventional holographic display techniques, which are the requirements of a sub-micron pixel pitch and ultra-high resolution for spatial light modulators (SLMs) to enlarge the viewing zone and screen size, can be addressed using ...

Holographic Three-Dimensional Virtual Reality and Augmented Reality Display Based on 4K-Spatial Light Modulators

open access: yesApplied Sciences, 2019
In this paper, we propose a holographic three-dimensional (3D) head-mounted display based on 4K-spatial light modulators (SLMs). This work is to overcome the limitation of stereoscopic 3D virtual reality and augmented reality head-mounted display.
