Abstract
A space-variant optical correlator is proposed on the basis of the fra ctional Fourier transform. The optical device uses as a recording medi um for the holographic filter a photorefractive Bi12GeO2 (EGO) crystal . The experimental results confirm the shift-variance properties. Some limitations that arise from the volume diffraction are also considere d. (C) 1996 Optical Society of America
