Abstract
Described are systems and methods for variable angle Raman spectroscopy, in which electromagnetic radiation will be caused to intersect the sample under investigation at a plurality of angles of incidence, so as to provide Raman scattering spectra at each angle. One example use of measuring such spectra at multiple angles of incidence is to enable evaluation at a plurality of depths within the sample. In many implementations, the range of the angles of incidence will include, and extend to either side, of the critical angle.
