Novel systems research and development
At the chair MST, novel systems utilizing coherent electromagnetic and utrasound waves are realized involving a cooperation network. Outstanding research achievements have been made in adaptive optics and wavefront control. Adaptive lenses were used to realize novel microscopes for studying the thyroid gland in transgenic organisms. Optical in-situ 3D shape measurement with keyhole access was performed for machine tools, enabling 100% quality control. The realized ultrasound-based systems allow flow measurements of liquid semiconductors, providing new insights into crystallization processes (photovoltaics).
