Frequency domain laser ultrasound microscopy for nanometric layer thickness imaging with GHz elastic plate resonances
Martin Ryzy, Guqi Yan, István Veres +6
Nanometric layer thickness imaging is crucial for fundamental research and characterization of micro fabricated devices. Here, we assess the potential of a non-contact opto-acousti…
A Linear State Space Model for Photoacoustic Imaging in an Acoustic Attenuating Media
Oliver Lang, Peter Kovacs, Christian Motz +3
In photoacoustic imaging, ultrasound waves generated by a temperature rise after illumination of light absorbing structures are measured on the sample surface. These measurements a…
A New Sparsification and Reconstruction Strategy for Compressed Sensing Photoacoustic Tomography
Markus Haltmeier, Michael Sandbichler, Thomas Berer +3
Compressed sensing (CS) is a promising approach to reduce the number of measurements in photoacoustic tomography (PAT) while preserving high spatial resolution. This allows to incr…
Compressed sensing and sparsity in photoacoustic tomography
Markus Haltmeier, Thomas Berer, Sunghwan Moon +1
Increasing the imaging speed is a central aim in photoacoustic tomography. This issue is especially important in the case of sequential scanning approaches as applied for most exis…
A Novel Compressed Sensing Scheme for Photoacoustic Tomography
Michael Sandbichler, Felix Krahmer, Thomas Berer +2
Speeding up the data acquisition is one of the central aims to advance tomographic imaging. On the one hand, this reduces motion artifacts due to undesired movements, and on the ot…
Single-Electron Transistor in Strained Si/SiGe Heterostructures
Thomas Berer, Dietmar Pachinger, Georg Pillwein +4
A split gate technique is used to form a lateral quantum dot in a two-dimensional electron gas of a modulation-doped silicon/silicon-germanium heterostructure. e-beam lithography w…
