Abstract
We propose what we believe to be a novel and simple method for optical symm etry filtering, using anisotropic self-diffraction in BaTiO3 crystals. This method allows us to distinguish a centrosymmetric pattern from a noncentro symmetric pattern easily with scale invariance. It is self-referential; no extra reference element is required. Both the theory and the experiment are demonstrated. (C) 1999 Optical Society of America. OCIS codes: 070.5010, 070.6110, 100.4550.
