Abstract
We demonstrate a fast optical scanning wave microscope. This acoustic microscope may be thought of as a noncontact (hence nondestructive) surface acoustic microscope. The key to obtaining a sufficient system signal to noise ratio without surface damage is tailoring of the generating optical distribution. This can be used to spread the optical power on the sample surface (preventing damage) and to focus the acoustic waves (increasing the amplitude). This paper introduces the optical scanning acoustic wave microscope, demonstrating some of its imaging capabilities, and discusses some of the ongoing work developing the techniques involved.
