Abstract

Magnetic phenomenon is one of the earliest physical phenomena realized by human. The technology of high sensitivity magnetic field measurement has been used in many applications such as geophysical prospection, aerospace engineering, earth-magnetism navigation, biomedicine, fundamental physics, and so on. With the development of laser technology, the study of atomic magnetometer makes great progresses for the past few decades. This paper reports a magnetic field sensor with optical resonant measurement. Experiments have demonstrated the scalar component of the magnetic field with the resonant precession frequency of the coherent atoms and the vector component with the Lock-in Amplifier (LIA) phase shift on the field angle.
