摘要：

The purpose of this paper is to experimentally demonstrate advantages of a multi-frequency ECT system. In this system, a precise crack imaging was achieved by using spectrograms obtained from an eddy-current probe multifrequency response. A complex signal containing selected sinusoidal components was used as an excitation, The results of measurements for various test specimens are presented. (C) 2000 Elsevier Science B.V.
