Inspection probe and system comprising a pulsed eddy current two-dimensional sensor array

摘要

A pulsed eddy current two-dimensional sensor array probe (12) for electrically conducting component inspection includes a drive coil (16) disposed adjacent to a structure under inspection, a pulse generator (20) connected to the drive coil (16) and operable to energize in a pulsed manner the drive coil (16) to transmit transient electromagnetic flux into the structure under inspection, and an array of sensors (18) arranged in a two-dimensional array and substantially surrounded by the drive coil (16) and operable to sense and generate output signals from the transient electromagnetic flux in the structure under inspection.
