Scanning Opto-Acoustic Microscope
The Picosecond Ultrasonics technique was first developed at Brown University in Prof. Humphrey Maris' group and has become a standard non-destructive technique that can be used to perform a wide range of ultrasonic experiments in thin films and more complex nanostructures. It has been increasingly employed to investigate other type and form of samples, such as liquid, biological samples etc.
