Ultrasonic paper testing


I am interested in study ultrasound propagation in paper by contact mode.

In the beginning I am interested only in the detection of the signal trough the paper (Lamb waves or similar) and velocity measurements in different directions.

I have knowledge of a commercial equipment for this propose that use bimorph ceramics.

I want to know if anybody knows a transducer for this application.


Best regards
