摘要：
Angular spectra of photoinduced light scattering (PILS) have been studied in PLZT ceramics. It is demonstrated that multiple-scattering effects must be taken into account to describe the main peculiarities of PILS in PLZT ceramics. A corresponding theory is developed in the Rytov approximation which allowed us to obtain from experiments the correlation function and dimensions of optical inhomogeneities as well as the field and angular dependencies of the holographic gain factor in PLZT.
