The use of structured light for object localization in diffusive media is discussed. The improvement of spatial resolution is shown. Phase detection of the spatially modulated light is proposed as a method for the localization of inclusions in the medium. Fast three-dimensional localization of an absorbing object based on finite-element analysis reconstruction is demonstrated with experimental data.
