DEVICE FOR DETECTING LOCAL DEFECTS OF CONDUCTING OBJECTS Russian patent published in 2007 - IPC G01N27/82

Abstract RU 2308026 C2

FIELD: nondestructive testing.

SUBSTANCE: method comprises 3D imaging of the object with the use of a matrix of the sources of the magnetic field and a set of high-sensitive magnetic field pickups. The source of the magnetic field is affected by the harmonic signal for sweeping by means of electrons. The converter of magnetic field is mounted above the source of the magnetic field at a given distance from it and is rigidly connected with it.

EFFECT: enhanced reliability.
