Abstract
Experimental results obtained from optically-scanned imaging of 3MHz pulsed acoustic fields are presented and discussed in the context of ultrasonic transducers used for B-scan medical imaging and industrial NDE.
The system described is shown to be capable of producing quasi-real time images of wideband pulses radiated by water-immersed transducers, for pulse durations down to 1µs in length. The results obtained are compared with those measured under C.W. excitation of the same test transducer. The physical limitations of the system are discussed in respect of the optical scanning process, the materials parameters and the signal processing requirements.
