Claim 0:
1. A method for defining parameters of a polycrystalline material, said method comprising:
illuminating, by a polarized Raman spectrometric apparatus, multiple locations of the polycrystalline material by multiple spots; wherein the polycrystalline material comprises grains;
collecting, by the polarized Raman spectrometric apparatus, radiation emitted from the multiple spots;
generating, by the polarized Raman spectrometric apparatus, a plurality of signals from the multiple locations of the polycrystalline material;
determining, by a computer and based on the plurality of signals, Raman peaks of the multiple locations;
determining, by the computer, and using a peak fitting algorithm, a distribution of Raman amplitudes of the Raman peaks; and
determining, by the computer, an average dimension of the grains based on the distribution of Raman amplitudes of the Raman peaks.
