Experimental results have confirmed that this incoherent optical correlator system possesses the capability of performing real-time pattern recognition.

A new optical system for real-time pattern recognition is presented, which mainly consists of a laser diode, an acoustooptic device with multi-transducer, a charge-coupled device and optical lenses.

Pattern recognition of casing defect and its forecasting is an important issue in the process of real-time monitoring and forecasting of casing damages.
