Resumen:
  A distortion-tolerant recognition process has been successfully implemented in an optical joint transform correlator operating with a LCTV in the input plane and a photorefractive crystal in the Fourier plane.  We have generated the reference by retaining the phase information of the Fourier Transform of a constrained phase-only minimum Euclidean distance synthetic discriminant function filter.  This gave rise to a process that successfully detects the target also for distortions not included in the training set.  Experimental and theoretical results are shown.
