The relaxor ferroelectric PbNi1/3Nb2/3O3 is studied by the non-steady-state photo-EMF technique at wavelength λ=457 nm corresponding to the light absorption edge of the crystal. This enables both the near-surface recording of diffusion charge gratings and photo-EMF signal excitation. The signal amplitude depends on the frequency of phase modulation of light, intensity and spatial frequency of the interference pattern. Analyzing these dependencies, we estimate the photoelectric parameters of the crystal - the type, value and relaxation time of photoconductivity, as well as the diffusion length of charge carriers. Keywords: non-steady-state photo-EMF, photoconductivity, relaxor ferroelectric.
