Detection of inhomogeneities in diffusive media using spatially modulated light

Not Accessible

Your library or personal account may give you access

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.
