Abstract
The principle of acousto-optic imaging is to combine coherent light and ultrasound in biological tissues to detect optical contrasts with a spatial resolution close to that of echography. Here we propose a model to describe the propagation of acoustically modulated light in a scattering medium. To do so, we derive a correlation diffusion equation from a correlation transport equation making a few approximations. We express solutions of this diffusion equation and compare them with Monte Carlo simulations in the case of uniform and localized insonifications.
