On Fourier Phase Retrieval from Differential Intensity Measurements with Applications to Wavefront Sensing

Simon Hubmer, Lukas Weissinger, Ronny Ramlau +1

In this paper, we consider Fourier phase retrieval from differential intensity measurements, i.e., the problem of determining the phase of a complex-valued function from a series o…

Quantitative Multi-Modal Optical Coherence Photoacoustic Elastography

Ekaterina Sherina, Lisa Krainz, Wolfgang Drexler +1

We present a novel multi-modal optical coherence photoacoustic elastography framework, which combines two imaging modalities, optical coherence tomography and photoacoustic tomogra…

Raster Scan Diffraction Tomography

Peter Elbau, Noemi Naujoks, Otmar Scherzer

Diffraction tomography is a widely used inverse scattering technique for quantitative imaging of weakly scattering media. In its conventional formulation, diffraction tomography as…

Pressure beneath a periodic travelling water-wave in constant-vorticity flow over a flat bed

Adrian Constantin, Nicolas Gindrier, Otmar Scherzer

We investigate within the framework of linear theory the behaviour of the total (hydrodynamic) pressure and of the dynamic pressure in a regular wave train which propagates at the…

Addendum on data driven regularization by projection

Martin Hanke, Otmar Scherzer

We study the stability of regularization by projection for solving linear inverse problems if the forward operator is given indirectly but specified via some input-output training…

Neural operators for solving nonlinear inverse problems

Otmar Scherzer, Thi Lan Nhi Vu, Jikai Yan

We consider solving a probably infinite dimensional operator equation, where the operator is not modeled by physical laws but is specified indirectly via training pairs of the inpu…
