Photonic-dispersion neural networks for inverse scattering problems [PDF]

open access: yesLight: Science & Applications, 2021
Inferring the properties of a scattering objective by analyzing the optical far-field responses within the framework of inverse problems is of great practical significance.

Uncertainty Quantification in Inverse Scattering Problems [PDF]

open access: yesEntropy
Inverse scattering problems seek anomalies in a medium given data measured after the interaction with emitted waves. Due to noise, predictions about the nature of these inclusions should be complemented with uncertainty estimates. To this end, we propose

Improved TV-CS Approaches for Inverse Scattering Problem [PDF]

open access: yesThe Scientific World Journal, 2015
Total Variation and Compressive Sensing (TV-CS) techniques represent a very attractive approach to inverse scattering problems. In fact, if the unknown is piecewise constant and so has a sparse gradient, TV-CS approaches allow us to achieve optimal ...

Quantum imaging and inverse scattering

open access: yesOptics Letters, 2010
We consider the inverse scattering problem that arises in two-photon quantum imaging with interferometric measurements. We show that the two-point correlation function of the field contains information about the scattering medium at a spatial frequency of twice the Rayleigh bandwidth. The linearized inverse problem, however, yields reconstructions with

Review of seismic inverse scattering migration and inversion

open access: yes地球与行星物理论评, 2021
With the shifting toward deeper, geologically more complex, and more subtle hydrocarbon reservoirs than before, the exploration of oil and gas resources is becoming more and more difficult.

Scattering and inverse scattering on ACH manifolds [PDF]

open access: yesJournal für die reine und angewandte Mathematik (Crelles Journal), 2008
We study scattering and inverse scattering theories for asymptotically complex hyperbolic manifolds. We show the existence of the scattering operator as a meromorphic family of operators in the Heisenberg calculus on the boundary, which is a contact manifold with a pseudohermitian structure.

Tracing multiple scattering trajectories for deep optical imaging in scattering media

open access: yesNature Communications, 2023
Multiple light scattering hampers imaging objects in complex scattering media. Approaches used in real practices mainly aim to filter out multiple scattering obscuring the ballistic waves that travel straight through the scattering medium.
