Inductively coupled Lamb wave transducers

Concept of inductively coupled transducer.

 

Two implementations of the inductively coupled transducer.



Movie showing robot probing an inductively coupled transducer. The robot was constructed by Anand Boscha. The movie (in wmv format) shows the robot approaching the transducer; the various Lamb wave reflections become visible on the screen as the probe coil is brought close to the transducer.
