PULSED EDDY CURRENT TWO-DIMENSIONAL SENSOR ARRAY INSPECTION PROBE AND SYSTEM

摘要

A pulsed eddy current two-dimensional sensor array probe (12) for electrical ly conducting component inspection includes a drive coil (16) disposed adjacent to a structure under inspection, a pulse generator (20) connected to the drive co il (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 driv e coil (16) and operable to sense and generate output signals from the transient electromagnetic flux in the structure under inspection.
