The method proposed here allows to perform a selection of a well defined subsurface volume in a turbid medium allowing SNR enhancement for functional imaging of the cortex. The principle consists in sequentially probing the biological tissue with light polarized linearly or circularly. The method and preliminary results obtained on phantoms are presented.
