Abstract
A multi-beam atomic sensor with three orthogonal helium vapor cells to guarantee the availability of4He magnetometer under different directions of magnetic field is proposed and tested, which demonstrates experimentally that dead zones of magnetic field measurement can be eliminated. Furthermore, with the special optical design, the multi-beam atomic sensor is also used for laser frequency stabilization simultaneously, which shows the possibility of reducing heading errors caused by the light shift effect.
