Abstract: A photorefractive nonlinear joint-transform correlator is demonstrated by utilizing the nonlinear intensity-dependent behavior of beam-fanning in a photorefractive barium titanate crystal. The results obtained reveal a narrowing of the correlation profile, and improved peak-to-side lobe ratio resulting in a better discrimination ability of the cormlator. The compressional beam-fanning nonlinearity is modelled for a simulation study in order to give a comparison with the experimental observation.
