ABSTRACT:
A transducer for use in a structural health monitoring system includes a single transducer element. The transducer includes a transmit assembly coupled to the single transducer element. This assembly is configured to produce a multi-cycle square wave drive signal for stimulating the transducer. Additionally, a transmit/receive switch coupled to the single transducer element is provided. This assembly is configured to isolate the drive signal from the receive assembly used to sense the electrical signal generated from any received elastic waves.
