Simultaneous Color Computer Generated Holography

SIGGRAPH Asia 2023 Conference Papers, 2023
Computer generated holography has long been touted as the future of augmented and virtual reality (AR/VR) displays, but has yet to be realized in practice. Previous high-quality, color holographic displays have made either a 3$\times$ sacrifice on frame rate by using a sequential color illumination scheme or used more than one spatial light modulator ...

4K-DMDNet: diffraction model-driven network for 4K computer-generated holography

Opto-Electronic Advances, 2023
Deep learning offers a novel opportunity to achieve both high-quality and high-speed computer-generated holography (CGH). Current data-driven deep learning algorithms face the challenge that the labeled training datasets limit the training performance ...

Complementary computer generated holography for aesthetic watermarking

Optics Express, 2012
We present herein an original solution for the watermarking of holograms in binary graphic arts without unaesthetic diffractive effect. It is based on the Babinet principle of complementary diffractive structures adapted to Lohmann-type computer generated holograms.

Multifocal co-plane metalens based on computer-generated holography for multiple visible wavelengths

Results in Physics, 2020
Traditional optical components need to accumulate optical path to control the wavefront. To achieve a desired function, several components are cascaded resulting in optical systems that are bulky and costly.

Perceptually Guided Computer-generated Holography [PDF]

London Imaging Meeting, 2022
Computer-Generated Holography (CGH) promises to deliver genuine, high-quality visuals at any depth. We argue that combining CGH and perceptually guided graphics can soon lead to practical holographic display systems that deliver perceptually realistic ...

Synthesizing optical spectra using computer-generated holography techniques

New Journal of Physics, 2021
Experimental control and detection of atoms and molecules often rely on optical transitions between different electronic states. In many cases, substructure such as hyperfine or spin-rotation structure leads to the need for multiple optical frequencies ...

Computer-Generated Hologram Based on Reference Light Multiplexing for Holographic Display

Applied Sciences, 2021
In this article, we propose a reference light wave multiplexing scheme to increase the information capacity of computer-generated holograms. The holograms were generated by different reference light waves and superimposed together as a multiplexed ...
