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…
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…
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…
Leveraging Real-Time Data Analysis and Multiple Kernel Learning for Manufacturing of Innovative Steels
Wolfgang Rannetbauer, Simon Hubmer, Carina Hambrock +1
The implementation of thermally sprayed components in steel manufacturing presents challenges for production and plant maintenance. While enhancing performance through specialized…
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…
On SCD Semismooth Newton methods for the efficient minimization of Tikhonov functionals with non-smooth and non-convex penalties
Helmut Gfrerer, Simon Hubmer, Ronny Ramlau
We consider the efficient numerical minimization of Tikhonov functionals with nonlinear operators and non-smooth and non-convex penalty terms, which appear for example in variation…
The MICADO first light imager for the ELT: off-axis performance of PSF reconstruction
Matteo Simioni, Daniel Jodlbauer, Carmelo Arcidiacono +14
The highest scientific return, for adaptive optics (AO) observations, is achieved with a reliable reconstruction of the PSF. This is especially true for MICADO@ELT. In this present…
On Phase Unwrapping via Digital Wavefront Sensors
Simon Hubmer, Victoria Laidlaw, Ronny Ramlau +2
In this paper, we derive a new class of methods for the classic 2D phase unwrapping problem of recovering a phase function from its wrapped form. For this, we consider the wrapped…
Singular Value and Frame Decomposition-based Reconstruction for Atmospheric Tomography
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 used f…
Predictive Modelling of Critical Variables for Improving HVOF Coating using Gamma Regression Models
Wolfgang Rannetbauer, Simon Hubmer, Carina Hambrock +1
Thermal spray coating is a critical process in many industries, involving the application of coatings to surfaces to enhance their functionality. This paper proposes a framework fo…
