Resumen

The optical implementation of a photorefractive fractional joint transforms correlator was studied. It was based on a non-degenerated four-wave mixing in a photorefractive crystal BSO. The fractional Fourier transform of the input scene, and a fractional Fourier transform of the reference image, were found interfere in the photorefractive material BSO to produce a phase hologram. The experimental results of the study of sensibility from the correlator to the rotation of the input patterns were presented.
