Description

As its name implies, the pulsed eddy current (PEC) method makes use of a short burst of excitation current, rather than continuous sinusoidal (CW) current as is the case with conventional eddy current probes. Reflected fields, including flaw signal fields, are therefore time-dependent in the pulsed case, and are characterized by peak signal amplitude, pulse arrival time and signal decay parameters, rather than amplitude and phase as in the CW case.
