摘要
An optically pumped magnetometer includes: a modulation unit which allows rectangular wave modulation to an angle of a polarization plane of probe light; a detector for detecting a change of the angle of the polarization plane of the probe light transmitted through a cell; and a differential circuit for obtaining a difference in light intensity between components separated by a polarization splitter. Thus, both a reduction of a light intensity noise of the probe light and a separation and reduction of a noise defined by an inverse of a frequency in a low frequency area can be achieved.
