A Wideband Magnetometer Implemented by the Optically Induced Fictitious Magnetic Field Technology

We propose a wideband magnetometer based on the classical M_{x} method realized with the multiple fictitious magnetic fields by applying a spatial light modulator and a microlens array.

Description
Summary:We propose a wideband magnetometer based on the classical M_{x} method realized with the multiple fictitious magnetic fields by applying a spatial light modulator and a microlens array. We give a brief theoretical description of the optically induced fictitious magnetic field and introduce the experimental setup of this magnetometer. Compared with the traditional magnetometers, the band of this magnetometer is user-defined and can cover up MHz order of magnitude, which is conducive to measure the interference magnetic field with wide frequency band.
