OPTICALLY PUMPED MAGNETOMETER, MAGNETOENCEPHALOGRAPHY METER, AND MRI DEVICE

摘要

An optically pumped magnetometer is one for measuring a magnetic field of a subject of interest utilizing optical pumping, and comprises: a non-magnetic cell in which at least an alkali metal is encapsulated and which has light transmissivity and heat resistance; a laser beam emission unit which emits a laser beam toward the cell to achieve the optical pumping of at least the alkali metal; a detection unit which receives the transmitted laser beam that has been transmitted through the cell and which detects a detection signal associated with the magnetic field; and a high-frequency voltage application unit which applies a high-frequency voltage to a pair of application sections arranged in the cell and which heats the cell by dielectric heating.
