Joint Transform Correlation technique is discussed
and Joint Transform Correlator experimental system with two optically addressed SLMS is designed.A series of experimental results have been obtained
including single target
multiple targets and noisy image recognititon.We have measured the image distortion sensitivity of this system
and the effects of LCLV'S nonlinear input-output character on correlation signds. Finally we have concisely discussed the way of ditortion-invariant image recognition by Joint Transform Correlator.
