Method of detecting a spatial magnetic field distribution of static and dynamic magnetic fields and magnetic field sensor arrangement

摘要

Method of recording a spatial magnetic field distribution of static and dynamic magnetic fields, which are caused by magnetic or magnetizable objects or objects which influence the magnetic field and which are located in a coordinate system Σ 'with the coordinates x', y 'and z', with the steps: a) Moving a magnetic field sensor arrangement, comprising several magnetic field sensors, which is located in a coordinate system Σ with the coordinates x, y and z, with several magnetic field sensors in an area with the coordinates x and y, in one spatial direction (y-direction) via a to measuring object and detecting the magnetic field distribution; b) shifting the magnetic field sensor arrangement in the orthogonal spatial direction (x-direction) by an amount equal to the length or width of an individual magnetic field sensor; c) moving the magnetic field sensor arrangement again in the y-direction over the object to be measured and recording the magnetic field distribution ; d) Repeat steps a) to c) up to a complete detection of the magnetic field distribution in a sectional plane, characterized in that the magnetic field sensor arrangement with equidistantly arranged magnetic field sensors is moved at a non-linear speed over the object to be measured, or the magnetic field sensor arrangement with equidistantly arranged magnetic field sensors is moved at a linear speed over the object to be measured, whereby a temporally non-linear acquisition of the data from the magnetic field sensors takes place.
