Paper Abstract

We present a new detection scheme for acousto-optic tomography, based on pseudo-random modulation of the utlrasound and illumination combined with hterodyne parallel speckle detection. This setup allows to perform tomographies inside several centimeter-thick scattering sample. Test experiments confirm the suitability of this method to perform tomographies inside various types of optically scattering media.
