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…
Singular Value-based Atmospheric Tomography with Fourier Domain Regularization (SAFR)
Lukas Weissinger, Simon Hubmer, Bernadett Stadler +1
Atmospheric tomography, the problem of reconstructing atmospheric turbulence profiles from wavefront sensor measurements, is an integral part of many adaptive optics systems. It is…
On the Intensity-based Inversion Method for Quantitative Quasi-Static Elastography
Ekaterina Sherina, Simon Hubmer
In this paper, we consider the intensity-based inversion method (IIM) for quantitative material parameter estimation in quasi-static elastography. In particular, we consider the pr…
3D Full Spectrum Fitting: Algorithm Comparison
Prashin Jethwa, Simon Hubmer, Ronny Ramlau +1
Full spectrum fitting is the prevailing method for extracting stellar kinematic and population measurements from 1D galaxy spectra. 3D methods refer to analysis of Integral Field S…
A Geometrical Acoustics based Focusing Algorithm for Layered Media in Medical Ultrasound
Simon Hackl, Simon Hubmer, Ronny Ramlau
Ultrasound imaging is a widely used, non-invasive diagnostic tool in modern medicine. A crucial assumption is a constant sound speed in the observed medium. For large scale sound s…
A Practical Guide to Optimizing Industrial Thermal Spraying through Comparative Multi-Objective Optimization
Wolfgang Rannetbauer, Simon Hubmer, Carina Hambrock +1
Achieving both high quality and cost-efficiency are two critical yet often conflicting objectives in manufacturing and maintenance processes. Quality standards vary depending on th…
