The Applied Spectroscopy group deals with the spectroscopic-technological analysis of process systems. This requires an interaction between the development of process-adapted spectroscopic methods, basic investigations at the molecular level, multivariate data analysis and molecular-dynamic simulations.
On the metrological side, the focus is on the development of contactless methods suitable for real-time process characterization. The main focus is on the development of methods based on inelastic Raman scattering, absorption and fluorescence spectroscopy.
On the process side, the working group shows a high degree of interdisciplinarity and develops strategies in close cooperation with various groups from the fields of pharmaceutical technology, bioprocess engineering and mechanical engineering (laser material processing).
The analysis and interpretation of optical measurement signals is primarily carried out by combining theoretical principles of molecular physics, chemistry and biology with methods of signal processing and multivariate data analysis. These results will also be compared with results from numerical simulations, for example in the field of laser welding of plastics.
