Abstract

See full text

A gradiometer in which a probe beam for reading sequentially passes through two magnetic field measurement regions to obtain signals according to magnetic flux densities of the respective regions is formed using an optically pumped magnetometer. In particular, in a gradiometer using a high sensitivity optically pumped magnetometer, a geometric arrangement enabling obtainment of a large signal from a dipole moment as a signal source is defined.
