We demonstrate the operation of a rotation sensor based on the nitrogen-14 (N) nuclear spins intrinsic to nitrogen-vacancy (NV) color centers in diamond. The sensor uses optical polarization and readout of the nuclei and a radio-frequency double-quantum pulse protocol that monitors N nuclear spin precession. This measurement protocol suppresses the sensitivity to temperature variations in the N quadrupole splitting, and it does not require microwave pulses resonant with the NV electron spin transitions. The device was tested on a rotation platform and demonstrated a sensitivity of 4.7°/ (13 mHz/), with a bias stability of 0.4 °/s (1.1 mHz).
我们展示了一种基于金刚石中氮空位（NV）色心固有的氮 - 14（N）核自旋的旋转传感器的运行情况。该传感器利用原子核的光偏振和读出以及监测N核自旋进动的射频双量子脉冲协议。这种测量协议抑制了对N四极分裂中温度变化的敏感度，并且不需要与NV电子自旋跃迁共振的微波脉冲。该装置在一个旋转平台上进行了测试，显示出4.7°/（13 mHz/）的灵敏度，偏置稳定性为0.4°/s（1.1 mHz）。
