Abstract
An improved optical pumping magnetometer with sequential polarization for measurement of weak magnetic fields involves a device which sequentially modifies the polarization either in the direction of the polarization or from clockwise to counterclockwise circular polarization. As a result of the sequential modification of the polarization, the magnetometer for measurement of the weak magnetic fields has excellent isotropy while still retaining a simple construction and a small overall dimension to the device by using only a single cell.
