摘要

PURPOSE: A nondestructive inspection apparatus which generates a gradient electromagnetic field is provided to accurately detect even a fine defect that is generated in the feed direction of an object or the perpendicular direction to the feed direction. ;CONSTITUTION: A nondestructive inspection apparatus comprises an electromagnetic field generating unit, a magnetic sensor array, a signal processing unit, and a display unit. The electromagnetic field generating unit(13) applies an electromagnetic field, which propagates in a direction different from the feed direction of an object, to the object. The magnetic sensor array(12) generates magnetic field sensing signals corresponding to the intensity of the electromagnetic field from the object. The signal processing unit(15) changes the magnetic field sensing signals to correspond to a display form. The display unit(16) displays the magnetic field sensing signals from the signal processing unit.;COPYRIGHT KIPO 2011
