Structural Health Monitoring based on Lamb waves is a promising technology for in-service inspection of aerospace structures. For the design of SHM systems in respect to different application requirements the visualisation of the wave propagation field is essential. As presented, the air-coupled ultrasonic scanning technique is a suitable methodology for this task, especially the recording of the complete wave propagation field by volume data files. These data files in combination with different analysis tools provide the basis for the design of actuators, sensors, signal processing and algorithms for damage detection. It has been shown that the signal of virtual sensors can be simulated using the scanned propagation field. It could be demonstrated that mode selective actuators are able to excite a particular Lamb wave mode in a CFRP plate. The design and manufacturing of reliable actuator and sensor networks are presented. Finally, a concept of damage detection in a helicopter tailboom has been shown.
