The world as a hologram [PDF]

open access: yesJournal of Mathematical Physics, 1994
According to ’t Hooft the combination of quantum mechanics and gravity requires the three‐dimensional world to be an image of data that can be stored on a two‐dimensional projection much like a holographic image.

Acoustic Hologram Reconstruction With Unsupervised Neural Network

open access: yesFrontiers in Materials, 2022
An acoustic hologram is crucial in various acoustics applications. The reconstruction accuracy of the acoustic field from the hologram is important for determining the performance of the acoustic hologram system.

Weighted Constraint Iterative Algorithm for Phase Hologram Generation

open access: yesApplied Sciences (Switzerland), 2020
A weighted constraint iterative algorithm is presented to calculate phase holograms with quality reconstruction. The image plane is partitioned into two regions where different constraint strategies are implemented during the iteration process.

Fourier Imager Network (FIN): A deep neural network for hologram reconstruction with superior external generalization [PDF]

open access: yesLight: Science & Applications, 2022
Deep learning-based image reconstruction methods have achieved remarkable success in phase recovery and holographic imaging. However, the generalization of their image reconstruction performance to new types of samples never seen by the network remains a

Fast Numerical Reconstruction of Integral Imaging Based on a Determined Interval Mapping

open access: yesApplied Sciences, 2023
In this paper, a fast numerical reconstruction of the integral imaging based on a determined interval mapping is proposed. To reduce the computation time, the proposed method employs the determined interval mapping instead of the use of magnification. In

Verification of Polarization Matching on the Hologram Recording Plane for the Implementation of an Optimized Digital Hologram Printing System

open access: yesFrontiers in Physics, 2022
Conventional studies on digital hologram printer have mainly been conducted on image generation and reconstruction such as multi-view image generation method, computer-generated hologram (CGH) and a method of displaying a wave-front for a 3D object ...

Safe hologram [PDF]

open access: yesModern Physics Letters A, 2020
We propose to describe the gauge sector of an asymptotically safe field theory in [Formula: see text] dimensions as a scalar theory on fixed AdS in [Formula: see text]-dimensions using the holographic dictionary.
