Abstract:
     The identity detector consists of impulse source, probe, amplifier, filter, A/D converter and computer. By means of the comparision between the complex natural frequency of the part to be measured and that of a standard part, the part defects are detected. By using the said detector, one single measurement is enough to determine if there are defects in the workpiece. Therefore, it can greatly raise detection speed and precision.
