Abstract

The non contact generation and detection of ultrasound has recently received considerable attention and the first industrial applications are now emerging. Attention has focused on optical methods and in particular the techniques of laser ultrasound. However there are many applications where the cost of the laser solutions to both generation and detection are prohibitive and other cases where the limitations of interferometric detection are decisive.
