Sound of nano (2013)
Journal Article

Ultrasound is widely used for imaging, measurement and diagnostics in the MHz region and is perhaps most familiar as a medical or non-destructive imaging or measurement tool. In the MHz frequency range the wavelength is typically measured in microns... Read More about Sound of nano.

Determination of crystallographic orientation of large grain metals with surface acoustic waves (2012)
Journal Article

A previously described laser ultrasonic technique known as spatially resolved acoustic spectroscopy (SRAS) can be used to image surface microstructure, using the local surface acoustic wave (SAW) velocity as a contrast mechanism. It is shown here tha... Read More about Determination of crystallographic orientation of large grain metals with surface acoustic waves.

CHOTs optical transducers (2011)
Journal Article

Laser ultrasonics conventionally use direct absorption in the sample to generate ultrasound and monitor the sample to detect the ultrasound. However, in some circumstances there are significant advantages to using an optical transducer - a device to... Read More about CHOTs optical transducers.
