PZT array technique in active Lamb wave structural health monitoring is researched.The application problems of traditional matrix PZT array are analyzed.Echo type circle PZT array is designed.Its characters and the signal acquision process are presented.Based on the time reversal imaging technology
the damage can be detected.Experiment indicates that circle PZT array can overcome the problems of traditional matrix array
such as monitoring area and the monitoring ability difference of the signals.Shortcoming of circle PZT array is analyzed.
