“…In this work we consider an alternative approach to the inverse source problem which, in some sense, is in the spirt of several recently proposed hybrid imaging modalities [3,6,11,20,26,31,37]. In these methods, a wavefield is used to control the material properties of a medium of interest, which is then probed by a second wavefield [6,7,4,14,12,13,35,27,24,15,29,30]. Here we exploit the acoustoelectric effect, in which the density of charge carriers and conductivity are spatially modulated by an acoustic wave [28,33].…”

We propose a method to reconstruct the electrical current density inside a conducting medium from acoustically-modulated boundary measurements of the electric potential. We show that the current can be uniquely reconstructed with Lipschitz stability. We also perform numerical simulations to illustrate the analytical results, and explore the partial data setting when measurements are taken only on part of the boundary.
