基于金刚石中不同轴向NV色心的磁力计的探讨

Discussion on Magnetometer Based on Different Axial NV Centers in Diamond

本文从理论上研究了利用金刚石中四个不同轴向的NV色心来测量静磁场的方法。研究结果显示通过测量光探测磁共振谱(ODMR),提取出NV坐标系下的场强和极化角信息。最后利用多个NV色心即可重构出在实验室坐标下的磁场。

In the paper,the method of measuring magnetostatic field using four different axial NV centers in diamond is studied theoretically.The research results show that the field strength and polar angle in the NV frame of reference system can be extracted by measuring the optical detection magnetic resonance spectrum.Finally,the detected magnetic field relative to a fixed laboratory reference frame was reconstructed from the information acquired by the multi-NV sensor.
