Abstract:
The present invention relates to a vector magnetometer for measuring the components of an ambient magnetic field. This vector magnetometer comprises an optically pumped scalar magnetometer (2′), a pair of conductive windings (Ex,Ey) having distinct axes (Ox, Oy) and powered by two generators (Gx, Gy) having distinct frequencies. The RF coil (56) of the scalar magnetometer and the conductive windings (Ex,Ex) are mechanically integral with a swivel support (85) mounted on swivel means. The axis of the RF coil is in the same plane as the axes Ox, Oy. The support is swivelled so that this plane is substantially orthogonal to the ambient magnetic field.
