title: Photorefractive time differentiation of coherent optical images.
abstract: Two-beam coupling in photorefractive BaTiO(3) is used to perform time differentiation of time-varying coherent phase and amplitude images. Differentiation of one-dimensional signals and two-dimensional images is performed.
