【Abstract】 A hybrid opto electronic optical fiber detection system based on quasi joint transform correlation(QJTC) is proposed.The system can overcome the drawback of the overall small size of the joint transform spectrum in a conventional joint transform correlator(CJTC).The experiment results of optical fiber detection show the system can successfully perform the defect detection of optical fibers.Furthermore,it has higher discrimination comparing with the CJTC.
