The FID Vector Geomagnetic Quantum Magnetometer is a high-precision magnetic field measurement instrument based on optical magnetic resonance principles.

It simultaneously measures the intensity and direction of the Earth’s magnetic field—including inclination and declination—enabling true three-dimensional vector field measurement.

Utilizing free induction decay (FID) signal detection technology, the instrument achieves pT-level sensitivity, while delivering excellent stability and strong resistance to environmental interference.

All core components, including the quantum polarization probe, RF system, and signal processing module, are independently developed, ensuring high reliability and consistent performance.
