Variational source conditions and stability estimates for inverse electromagnetic medium scattering problems
Frederic Weidling, Thorsten Hohage
This paper is concerned with the inverse problem to recover the scalar, complex-valued refractive index of a medium from measurements of scattered time-harmonic electromagnetic wav…
Regularized Newton Methods for X-ray Phase Contrast and General Imaging Problems
Simon Maretzke, Matthias Bartels, Martin Krenkel +2
Like many other advanced imaging methods, x-ray phase contrast imaging and tomography require mathematical inversion of the observed data to obtain real-space information. While an…
Convergence Rates for Exponentially Ill-Posed Inverse Problems with Impulsive Noise
Claudia König, Frank Werner, Thorsten Hohage
This paper is concerned with exponentially ill-posed operator equations with additive impulsive noise on the right hand side, i.e. the noise is large on a small part of the domain…
Pinsker estimators for local helioseismology
D. Fournier, L. Gizon, M. Holzke +1
A major goal of helioseismology is the three-dimensional reconstruction of the three velocity components of convective flows in the solar interior from sets of wave travel-time mea…
Verification of a variational source condition for acoustic inverse medium scattering problems
Thorsten Hohage, Frederic Weidling
This paper is concerned with the classical inverse scattering problem to recover the refractive index of a medium given near or far field measurements of scattered time-harmonic ac…
