The role of average spontaneous polarization of the polydomain sample on the macroscopic dielectric response is analyzed. The measurement method of average spontaneous polarization using optical methods is suggested and analyzed. The presented analysis is focused on the computation of optical properties near ferroelectric domain walls. The computation of refractive index in the regions near neutral domain walls is presented. Since it is known that the refractive index depends on the configuration of the crystal lattice within a particular domain and on the internal and external electric fields, the obtained results will be used for a suggested method of 3D imaging of ferroelectric domain walls and internal electric fields using digital holographic interferometry.
