Piezoelectric Transducers for Quantitative NDE
Piezoelectric transducers are undoubtedly one of the major elements for use in ultrasonic NDE. and our program essentially was involved for the last nine months in what you might call the NDE of NDE transducers, sort of NDE. Hopefully, we're not multiplying two small numbers together here. So, what I'd like to do is just give a summary of what we have been doing and tell you how far up on the learning curve we are.
