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.

Fluorescence optical tomography (FOT) is an imaging technology that localizes fluorescent targets in tissues. FOT is unstable and of poor resolution in strongly scattering media where the propagation of multiply-scattered light is highly diffusive. We study a hybrid imaging modality called fluorescent ultrasound-modulated optical tomography (fUMOT). It combines FOT with acoustic modulation to produce high-resolution images of optical properties.
