Applications of X-Ray Holography

open access: yesInternational Journal of Optics, 2021
X-ray holography is widely used in material, biology, and industry fields due to its potential to measure the microstructure and dynamic change of objects.

Holography in the invisible. From the thermal infrared to the terahertz waves: outstanding applications and fundamental limits

open access: yesLight: Advanced Manufacturing, 2022
Since its invention, holography has been mostly applied at visible wavelengths in a variety of applications. Specifically, non-destructive testing of manufactured objects was a driver for developing holographic methods and all related ones based on the ...

Polarization fields in GaN/AlN nanowire heterostructures studied by Off axis holography [PDF]

open access: yes, 2013
In this work, we present an off-axis holography study of GaN/AlN heterostructured nanowires grown by plasma-assisted molecular-beam epitaxy. We discuss the sample preparation of nanowire samples for electron holography and combine potential profiles ...

Monopoles and holography [PDF]

open access: yesJournal of High Energy Physics, 2011
We present a holographic theory in AdS_4 whose zero temperature ground state develops a crystal structure, spontaneously breaking translational symmetry. The crystal is induced by a background magnetic field, but requires no chemical potential. This lattice arises from the existence of 't Hooft-Polyakov monopole solitons in the bulk which condense to ...

Color Holography for the Documentation and Dissemination of Cultural Heritage: OptoClonesTM from Four Museums in Two Countries

open access: yesJournal of Imaging, 2019
True-color holograms, as they are the most advanced and realistic three-dimensional images obtainable with current technologies, can become valuable tools for the preservation, documentation and diffusion of cultural heritage.

Holographic Protection of Chronology in Universes of the Godel Type [PDF]

open access: yes, 2002
We analyze the structure of supersymmetric Godel-like cosmological solutions of string theory. Just as the original four-dimensional Godel universe, these solutions represent rotating, topologically trivial cosmologies with a homogeneous metric and ...

Spin holography [PDF]

open access: yesPhysical Review Letters, 1994
The interference of the directly emitted photoelectron wave and the wave scattered coherently by neighboring atoms gives holographic fringes in the photoelectron emission intensity $I(\hat{\bf R})$. In the electron emission holography technique in surface physics, $I(\hat{\bf R})$ is inverted holographically to give a 3D-image of the environment of the

Synthesis and characterization of ZnO thin film by low cost modified SILAR technique

open access: yesAIMS Materials Science, 2016
The ZnO thin film is prepared on Fluorine Tin Oxide (FTO) coated glass substrate by using SILAR deposition technique containing ZnSO4.7H2O and NaOH as precursor solution with 150 deeping cycles at 70 °C temperature.

Recent advances in multi-dimensional metasurfaces holographic technologies

open access: yesPhotoniX, 2020
Holography has attracted tremendous interest due to its capability of storing both the amplitude and phase of light field and reproducing vivid three-dimensional scenes. However, the large pixel size, low resolution, small field-of-view (FOV) and limited
