AI Technical Summary
The existing continuous optical magnetic resonance imaging (CMRI) technology has insufficient sampling rate in the frequency sweep method for magnetic field measurement, which cannot meet the high sampling rate requirements of some application scenarios and limits its application in fields such as power systems.
A rapid quantum-controlled magnetic measurement method using slice-locked frequency is employed. By employing segmented coarse frequency sweeping and data fitting, the frequency range of the trough is quickly determined. Furthermore, fine frequency sweeping is used to further improve the microwave modulation time, thereby increasing the sampling rate of quantum measurement.
It significantly improves the sampling rate of magnetic field measurements, especially in scenarios requiring high sampling rates, such as AC and DC current sampling in power systems, achieving higher measurement efficiency and accuracy.
