Imaging Techniques

Research in the field of imaging techniques means designing and developing imaging techniques with high spatial and temporal resolution for the measurement of phase, component and temperature distributions in multiphase flows. Thereby methods for automated image analysis and data fusion for the process and multiphase flows diagnostics play an elementary role. A practical objective is an improved experimental flow diagnostics and multiphase flow measurement in different application areas.
