Abstract: Crystallites in lead ziriconate-titanate films have been studied using the technique of nonlinear optical polarization microscopy. 2D maps of the Stokes parameters $S_0$, $S_1$, $S_2$, $S_3$ are determined. Nonlinear polarization components are analyzed.

Keywords: PZT, nonlinear optical microscopy, second harmonic generation, spherulites, Stokes parameters.
