TY - GEN A1 - Schadow, Florian T1 - Air-coupled ultrasonics: experimental realization N2 - This presentation is an overview of experimental realization of air-coupled ultrasonic testing. Focusing transducers based on ferroelectrets are presented. Inspection results of natural defects like impact damage and delamination of composite structures are shown and challenges relating to the propability of detection of defects are pointed out.
