  Ultrasound modulated optical tomography, also called acousto-optics
tomography, is a hybrid imaging modality that aims to combine the high contrast
of optical waves with the high resolution of ultrasound. We follow the model of
the influence of ultrasound modulation on the light intensity measurements
developed in [Bal Schotland PRL 2010]. We present sufficient conditions
ensuring that the absorption and diffusion coefficients modeling light
propagation can locally be uniquely and stably reconstructed from the
corresponding available information. We present an iterative procedure to solve
such a problem based on the analysis of linear elliptic systems of redundant
partial differential equations.
