MODE OF MEASURING MAGNETIC FIELDS BY ELECTRONIC OPTICAL METHOD Russian patent published in 2007 - IPC G01R33/02 

FIELD: the invention refers to measuring technique of magnetic fields and may be used in flaw detection of conductors and magnetic conductors.

SUBSTANCE: the mode of measuring the tension of a magnetic field includes using of electronic optical moiré effect emergent at imposition of shadowgraph image of the grid distorted by a magnetic field on the undistorted image of the grid. In accordance with the magnitude of grid distortion conditioned by deviation of an electrons beam in the measured magnetic field by Lorentz power it is possible to judge about the tension magnitude of the magnetic field. Peculiarity of the method is in that grid shadowgraph image on the screen of an electron diffractometer received in absence of the measured magnetic field is used in quality of the distorted grid image and imposition of the mentioned images is executed by way of sequential exhibit on one and the same photographic plate of distorted and undistorted grid images.

EFFECT: provides visualization of distribution of magnetic field of any complexity and high accuracy of measuring.
