ABSTRACT:
A method and apparatus for the noninvasive real-time characterization of samples using coherent backscattering is disclosed. The sample is illuminated by a laser, and the radiation that is coherently backscattered is measured. The line width or line shape of the coherent backscattered radiation, or in some cases just the existence of coherent backscatter, is then used to characterize the sample under test. This characterization is then used for the real time control of a process acting upon the sample.
