A diagram depicting the equipment used to drive the transducer (Tx) vibration system. A sinusoidal signal is output from a function generator and then amplified to drive the voice-coil actuator. The voice-coil was mechanically secured to the leaf spring and the Tx was secured to the rest of the system through a custom fixture, allowing the entire system to vibrate. Shear waves are generated by the motion of the transducer in contact with the object’s surface. Shear waves were observed using standard pulse-echo detection.
