On Regularization via Frame Decompositions with Applications in Tomography
Simon Hubmer, Ronny Ramlau, Lukas Weissinger
In this paper, we consider linear ill-posed problems in Hilbert spaces and their regularization via frame decompositions, which are generalizations of the singular-value decomposit…
Adaptive optics imaging with a pyramid wavefront sensor for visual science
Elisabeth Brunner, Julia Shatokhina, Muhammad Faizan Shirazi +6
The pyramid wavefront sensor (P-WFS) has replaced the Shack-Hartmann (SH-) WFS as sensor of choice for high performance adaptive optics (AO) systems in astronomy because of its fle…
Robust and bias-free localization of individual fixed dipole emitters achieving the Cramér Rao bound
Fabian Hinterer, Magdalena C. Schneider, Simon Hubmer +5
Single molecule localization microscopy has the potential to resolve structural details of biological samples at the nanometer length scale. However, to fully exploit the resolutio…
Phase-contrast THz-CT for non-destructive testing
Peter Fosodeder, Simon Hubmer, Alexander Ploier +3
A new approach for image reconstruction in THz computed tomography (THz-CT) is presented. Based on a geometrical optics model containing the THz signal amplitude and phase, a novel…
