Abstract :
The implementation of a nonzero-order joint transform correlator using double ports Mach-Zehnder interferometric technique is proposed and demonstrated. This approach can directly remove the zero-order joint power spectrum in one step and perform the nonzero-order optical correlation. Experimental results are presented and discussed.
