Abstract
Scattering of an arbitrary probe beam by a set of holographic gratings formed by photoinduced light scattering (PILS) and holographic-type p arametric scattering (HTPS) in a Lithium tantalate crystal is studied. A new kind of diffraction in photorefractive media, the anisotropic ' 'Venetian blind'' diffraction effect involving gratings formed by o-o- type PILS, is observed. This diffraction is shown to be a suitable ins trument for studying dynamic and statistical properties of holographic gratings formed in a crystal.
