Abstract

See full text

An optically pumped magnetometer having a single optical axis using atomic electron spin or nuclear spin includes a detection unit configured to detect an angle of a polarization plane of probe light having components of linear polarization and a modulation unit configured to apply a modulation to the angle of the polarization plane of the probe light having the components of linear polarization. The modulation unit is configured to control an offset in applying the modulation to the angle of the polarization plane of the probe light having the components of linear polarization according to the angle of the polarization plane of the probe light detected by the detection unit.
