We present a consistent experimental and theoretical study of non-Bragg orders observed in dynamic selfdiffraction on thick phase holograms in a photorefractive polymer that showed a strong refractive-index modulation amplitude. We demonstrate experimentally how the diffraction into non-Bragg orders can be used for image processing and as an independent evaluation method for the optical-photorefractive properties of the polymers.
