Design of a Unipolar Ultrasonic Pulser Generator and Receiver for Applications to Quantitative NDE
We recently developed and tested a prototype ultrasonic nondestructive test instrument that produces unipolar stress pulses in pulse-echo mode. The use of unipolar pulses instead of bipolar pulses offers significant increases in bandwidth. This new instrument should be useful in material processing, characterization and flaw detection and sizing applications over a range of flaw radii which are not accessible using conventional pulse/echo equipment.
