MAGNETIC SENSING METHOD, ATOMIC MAGNETOMETRIC SENSOR, AND MAGNETIC RESONANCE IMAGING APPARATUS

摘要

PPROBLEM TO BE SOLVED: To extend a measuring frequency band in a magnetic sensing method, an atomic magnetometric sensor and a magnetic resonance imaging apparatus. PSOLUTION: A group of atoms contained in a cell is irradiated with pump light having a circularly polarized component and probe light having a linearly polarized component to improve the magnetic sensing method utilizing a rotation angle of a plane of polarization of the probe light before and after passing the cell. A magnetic field of a direction in which the pump light enters an intersecting region is provided with a gradient, and in this state, irradiation of the pump light and probe light is carried out to acquire information on the rotation angle of the plane of polarization of the probe light before and after passing the cell.
