Extending the Imaging Depth of Field through Scattering Media by Wavefront Shaping of Non-Diffraction Beams

open access: yesPhotonics, 2023
Increasing the depth of field (DOF) is a crucial issue for imaging through scattering media. In this paper, an improved genetic algorithm is used to modulate the wavefront of light through scattering media, by which high-quality refocusing and imaging ...

Coherent light scattering from a two-dimensional Mott insulator [PDF]

open access: yes, 2011
We experimentally demonstrate coherent light scattering from an atomic Mott insulator in a two-dimensional lattice. The far-field diffraction pattern of small clouds of a few hundred atoms was imaged while simultaneously laser cooling the atoms with the ...

Application of the diffraction trace formula to the three disk scattering system [PDF]

open access: yes, 1996
The diffraction trace formula ({\em Phys. Rev. Lett.} {\bf 73}, 2304 (1994)) and spectral determinant are tested on the open three disk scattering system. The system contains a generic and exponentially growing number of diffraction periodic orbits.

Relationship between Internal Stress Distribution and Microstructure in a Suspension-Sprayed Thermal Barrier Coating with a Columnar Structure

open access: yesQuantum Beam Science, 2023
The suspension plasma spray (SPS) method is expected to become a novel coating method because it can achieve various microstructures using a suspension with submicron spray particles. Thermal barrier coatings (TBCs) with a columnar structure, which might

Diffractive scattering [PDF]

open access: yesJournal of Physics G: Nuclear and Particle Physics, 2002
We discuss basic concepts and properties of diffractive phenomena in soft hadron collisions and in deep-inelastic scattering at low Bjorken-x. The paper is not a review of the rapidly developing field but presents an attempt to show in simple terms the close inter-relationship between the dynamics of high-energy hadronic and deep-inelastic diffraction.

Diffraction of an electromagnetic wave on a countless number of scatterers

open access: yesВісник Харківського національногоуніверситету імені В.Н. Каразіна. Серія: Радіофізика та електроніка, 2022
Topicality. The task of finding the radar cross-section (RCS) of complex objects is of great importance. Usually, when creating radar stations, RCS is measured on real targets.

Inelastic Hadron Diffraction in High Energy Elastic Scattering of Nuclei [PDF]

open access: yes, 2001
The r\^{o}le of inelastic diffraction in elastic scattering of nuclei is studied in the formalism of \emph{diffractive limit}. The results obtained for scattering of the $\alpha$--particles on light nuclei show that the nucleonic diffraction is ...

Angle Resolved Scattering Measurement of Multiple Spherical Particles by Fourier Transform

open access: yesIEEE Photonics Journal, 2021
In this paper, we report that the far field diffraction pattern of a specimen which is consisting of an array of spherical particles enables the determination of the size and refractive index of each scattering sphere.

Diffraction at HERA and the Confinement Problem [PDF]

open access: yes, 2000
We discuss HERA data on the high energy behavior of the total gamma*p cross section and on diffraction in deep inelastic scattering. We outline their novelty in comparison with diffraction in high energy hadron hadron scattering.
