Abstract:

This paper reports on investigations of air-coupled ultrasonic imaging techniques which are part of the German research project MaTech. Project partners are Airbus, Bremen; Ingenieurbüro Dr Hillger, Braunschweig; and Intellige NDT, Erlangen, with DLR, Braunschweig as a subcontractor.

One task is the development of a modular ultrasonic imaging system which opens the possibility of basic research of air-coupled ultrasonic techniques for composites.

The development and construction of special transducers for air-coupling and the development of a system for echo technique are further research tasks of the MaTech project. This paper presents the features of the demonstrator III and first results from investigations of transducers and their application to composites.
