The Airscan system typically uses spherically focused resonant transducers of 25 mm diameter and 38 mm focal length. Because of this performance, the systems can be operated in real time, without the need for signal averaging. It is particularly useful when inspecting aerospace laminates with complicated internal geometries. It is our experience that plate waves play a significant factor in the inspection of many materials and structures. This is particularly the case when inspecting honeycomb structures.
Many more materials are under investigation.
