Ultrasound NDT (non-destructive testing)

Hi all,

I've a question and I hope that I can get some answers here.

As what my project has tasked, and what my lecturer had said. He needs me to build a device for NDT Testing.

Currently the set up is that I would source for a transducer via olympus coupled with a USB oscilloscope capable of generating an AWG wave.

So the set up would be Transducer > Amplifier <> USB Oscilloscope > Laptop

USB oscilloscope : http://www.tiepie.com/en/products/Oscilloscopes/Handyscope_HS5
Ultrasound Transducer : http://www.olympus-ims.com/en/ultrasonic-transducers/immersion/

I've gotten in touch with the specialist from Olympus and he told me it isn't going to work since the USB oscilloscope coupled with a high gain amplifier is capable of powering and driving the transducer. I've feed-backed to my lecturer and he told me that this certainly can be done without the pulser-receiver.

I can't really find any source of this type of project or set-up on the net and I really hope someone here can advise me and if possible, providing some sort of aid or help since I am pretty helpless now.

Reverse engineer a commercial product. UT is an industry standard.

Hi,

I dont see a commercial product that uses AWG and amplifier to drive a UT. Those in the market are using pulser-receiver.

Maybe the market is teaching.

Like reinventing the wheel, so far they've all been quite round. A three cornered wheel might not be a success.

What's an AWG wave?

Ah, I think you're right, Dave. I use Arbitrary Function Generators often, but was confused when the OP mixed the term in with "oscilloscope":

USB oscilloscope capable of generating an AWG wave.

its not a term I have come across before
yeah maybe he meant USB oscillator ?? :)

Na. Acoustic waveguide

Ah, huh! That does sound more likely, but I suppose you can use either in an ultrasonic imaging application. Thanks for the link. :-)

Maybe. Dang acronyms.

Don,
I saw and did consider that one and thought ... No he said generator and I was thinking waveguide as just a transmission medium for that generated signal
but looking at some of the links your link gave suggest its an all in one solution :)

Isnt it fun speculating when we don't get all the info up front ;)

Ya gotta love the HP/Agilent gear, Mike :)

I wasted way too much time. :headbang:

I do indeed. :oldlove:
