ABSTRACT:
An apparatus and method for using frequency modulated diffusive photon-density waves propagating through a turbid medium such as tissue for detecting optical properties of objects and for imaging objects within the turbid medium. Frequency modulation enables real time differential measurement of the interaction of different colors with the object when the different colors are chosen such that they react the same with the medium but differently with the object. The method greatly simplifies optical imaging and increases the amount of information which may be obtained about the object.
