The acousto-optic effect is a phenomenon in which the presence of an acoustic wave changes the light transmission properties of an optical medium. Acousto-optic tomography (AOT) is a hybrid imaging method which takes advantage of this effect. The general idea is to modulate the optical properties of an optical medium by varying an acoustic wave, take optical measurements for each modulation, and use this enormous trove of data to solve a stable inverse problem.

Since the nature of the acousto-optic effect varies depending on the setting, AOT can actually be thought of as a collection of related methods. In this talk, I'll discuss the inverse problems that arise from AOT in a setting where acoustic perturbation of an optical medium results in a frequency shifting of the scattered light. This is joint work with Jeremy Hoskins and John Schotland.
