Abstract

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.
