PhD Positions in Laser Ultrasonic and Photothermal at the Laboratory for Acoustics and Thermal Physics, KU Leuven, Belgium

Laser ultrasonic and photothermal research of heterogeneous structures

Description: Laser excited acoustic and thermal waves have the interesting property that they can deliver information about material properties on locations which are inaccessible for other techniques. In this research we study reflection, transmission, diffraction and nonlinear effects of thermal and elastic waves from the sub-Hz till GHz range using heterodyne diffraction, stroboscopic interferometric imaging, IR thermography and advanced data processing techniques (Gabor transformation, neural network recognition). In this way, in a non-contact way, it is possible, besides the elastic characterization of materials, to determine their depth sturcture, and to detect and identify sub-surface defects.

Photothermal, dielectric and laser ultrasonic investigation of frequency dependent thermophysical properties of soft mat

Description: The transition from a liquid to a solid state of matter sometimes goes along with a colorful and complex pallet of physical properties, which leads to interesting technological applications. Molecules in liquid crystalline compounds (LCD-displays) are aligning or show a liquid-like layered structure. Supercooled liquids (polymers, heat storage materials, speed-dependent mechanical coupling fluids) behave solid-like or liquid-like depending on the time scale of observation. Some materials (memory alloys) have a shape memory when cooling. In some gels the elastic wave velocity is extremely small, leading to spectacular effects. Using thermal, elastic and dielectric spectroscopy we study these strongly frequency and temperature dependent thermo-elastic phenomena in the sub-Hz – GHz range. For this we use IR thermography, photopyroelectric spectroscopy, dielectric spectroscopy and laser heterodyne diffraction and optical interferometry.
