Local optical properties of a biological tissue can provide useful information to improve medical diagnosis. However, non-invasive optical imaging deep inside the tissue remains a challenge, because of strong light scattering. The use of the acousto-optic effect between the light and the ultrasound (US) was proposed as a solution to achieve high-resolution images of optical contrast deep inside the tissue : US modulated optical tomography (UOT) [1]. So far, UOT was developed on experimental optical bench with focus US, requiring several minutes for data acquisition. The challenge for a clinical use of UOT is the acceleration of the data acquisition by one order of magnitude without degradation of the signal-to-noise ratio.
