| 摘要 |
The invention relates to a process for testing of a workpiece by means of eddy currents induced by a field coil in the workpiece and from which a measurement signal is obtained by means of a measurement sensor, a pattern signal representative of a workpiece fault being generated, a correlation function of the measurement signal acquired by the sensor with the pattern signal being determined, and the correlation function being evaluated in order to detect a fault in the workpiece. The invention furthermore relates to a device for executing the process.
