摘要
A hybrid opto-electronic optical fiber inspection system based on a quasi-joint transform correlator is proposed. The system can overcome the drawback of the overall small size of the joint transform spectrum in a conventional JTC. Experiment results show the system can successfully perform the defect detection of optical fibers. Furthermore, it has higher discrimination comparing with the conventional JTC.
