Abstract
To measure a magnetic field strength at each scan spacing s which is smaller than a loop size by scanning a magnetic field sensor (loop antenna) of the loop size. A magnetic field strength distribution is determined with spatial resolution of the spacing s along a scan direction, by performing arithmetic processing including addition and subtraction in relation to each of the measured magnetic field strength values. It is to be noted that the magnetic field sensor may be a magnetic field sensor array with plural magnetic field sensors placed at the spacing s.
