Claim 11:
12. A polarized Raman spectrometric system for defining parameters of a polycrystalline material, the polarized Raman spectrometric system comprising:
a polarized Raman spectrometric apparatus that is configured to:
illuminate multiple locations of the polycrystalline material by multiple spots; wherein the polycrystalline material comprises grains;
collect radiation emitted from the multiple spots; and
generate a plurality of signals from the multiple locations of the polycrystalline material;

a computer that is configured to:
determine, based on the plurality of signals, Raman peaks of the multiple locations;
determine, using a peak fitting algorithm, a distribution of Raman amplitudes of the Raman peaks; and
determine an average dimension of the grains based on the distribution of Raman amplitudes of the Raman peaks.
