| description | The invention discloses a compact magnetic signal measurement system and method based on optical magnetic resonance. The compact magnetic signal measurement system comprises a laser unit; the magnetic probe unit is arranged at the light emitting end of the laser unit; and the signal processing unit is located at the output end of the magnetic probe unit, receives the light current signal output by the magnetic probe unit, converts the received light current signal into a light voltage signal, and converts a corresponding frequency value into a magnetic field value by locking a dispersion curve zero crossing point corresponding to a light signal absorption peak. The compact magnetic signal measurement system is simple in structure, only needs to be composed of the laser light source, the probe unit and the signal processing unit, is simple in probe process, is suitable for large-scale production, is low in technical implementation requirement, and can detect magnetic field signals which change in real time und |
