초록
The NDT(nondestructive test) using pulse echo method with piezoelectric transducers and the system for NDT including image processing were studoed. The system consisted of pulse generator and receiver, two step motors for X-Y scanner, PC-Scope for data aquisition and PC-Lab for trigger and motor driving. We tested and estimated at one point under the following conditions : 1) just water, 2) Aluminum without any crack and 3) Aluminum with hole. The estimated NDT result of whole area (point :
