Electroelastic guided wave dispersion in piezoelectric plates: spectral methods and laser-ultrasound experiments
Daniel A. Kiefer, Georg Watzl, Katharina Burgholzer +2
Electroelastic waves in piezoelectric media are widely used in sensing and filtering applications. Despite extensive research, computing the guided wave dispersion remains challeng…
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…
Linking information theory and thermodynamics to spatial resolution in photothermal and photoacoustic imaging
Peter Burgholzer, Guenther Mayr, Gregor Thummerer +1
In this tutorial, we combine the different scientific fields of information theory, thermodynamics, regularization theory and non-destructive imaging, especially for photoacoustic…
Laser excited super resolution thermal imaging for nondestructive inspection of internal defects
Samim Ahmadi, Julien Lecompagnon, Philipp Daniel Hirsch +4
A photothermal super resolution technique is proposed for an improved inspection of internal defects. To evaluate the potential of the laser-based thermographic technique, an addit…
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…
