Information multiplexing from optical holography to multi-channel metaholography

open access: yesNanophotonics, 2023
Holography offers a vital platform for optical information storage and processing, which has a profound impact on many photonic applications, including 3D displays, LiDAR, optical encryption, and artificial intelligence.

Absorbing new subjects: holography as an analog of photography [PDF]

open access: yes, 2006
I discuss the early history of holography and explore how perceptions, applications, and forecasts of the subject were shaped by prior experience. I focus on the work of Dennis Gabor (1900–1979) in England,Yury N. Denisyuk (1927-2005) in the Soviet Union,

Scale holography [PDF]

open access: yesThe European Physical Journal C, 2018
We present a new correspondence between a d-dimensional dynamical system and a whole family of (d+1)-dimensional systems. This new scale-holographic relation is built by the explicit introduction of a dimensionful constant which determines the size of the additional dimension.

Robust Holographic Reconstruction by Deep Learning with One Frame

open access: yesPhotonics, 2023
A robust method is proposed to reconstruct images with only one hologram in digital holography by introducing a deep learning (DL) network. The U-net neural network is designed according to DL principles and trained by the image data set collected using ...

Effect of gold nano-particles on switch-on voltage and relaxation frequency of nematic liquid crystal cell

open access: yesAIP Advances, 2011
We report the observation of large changes in the electro-optical properties of nematic liquid crystal (NLC) due to inclusion of small concentration of 10 nm diameter gold nanoparticles (GNPs).

Holostereosynthesis: An Improvement to Louis Lumière’s Photostereosynthesis Technique

open access: yesApplied 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.

Compressive Holographic Video [PDF]

open access: yes, 2016
Compressed sensing has been discussed separately in spatial and temporal domains. Compressive holography has been introduced as a method that allows 3D tomographic reconstruction at different depths from a single 2D image.

Shifting perspectives: holography and the emergence of technical communities [PDF]

open access: yes, 2005
Holography, the technology of three-dimensional imaging, has repeatedly been reconceptualised by new communities. Conceived in 1947 as a means of improving electron microscopy, holography was revitalized in the early 1960s by engineer-scientists at ...

Nanooptical elements for visual verification

open access: yesScientific Reports, 2021
This paper focuses on the development of flat diffractive optical elements (DOEs) for protecting banknotes, documents, plastic cards, and securities against counterfeiting.
