Physical Acoustics Lab

From Wikipal

Welcome

The Physical Acoustics Laboratory (PAL) is part of the Department of Geosciences at Boise State University. Our interests are many, but center around wave propagation in disordered media for applications in Geophysics. Particularly, we are interested in extracting information from multiply scattered waves in heterogeneous media. In the lab, these waves are recorded via noncontacting techniques. For a more complete list of ongoing research at the PAL click, see Research Topics or the papers page.

Measured surface wave scattering from a groove

For example, this snapshot of the wavefield is described in this article. If you don't want to read, go see the movie. When you put many of these grooves (close) together, we see multiple scattering.

Multiply scattered waves pose a challenge in imaging, but also an opportunity.

The picture on the right is a comparison of a direct estimate of the Green function and the result of cross-correlating of waves bouncing around in granite.
