In BaTiO3 crystals possessing bulk photovoltaic behavior a photoinduced polarized Rayleigh scattering was observed. The results show that illumination of BaTiO3 crystals creates an inhomogeneous distribution of spontaneous polarization (photofluctuations) which are responsible for both effects, the bulk photovoltaic effect and the polarized Rayleigh scattering. The pseudo-Jahn-Teller effect which was introduced earlier for other photoferroelectric phenomena is assumed to be responsible for the creation of these photoinduced fluctuations.
