摘要: 原子对磁场的高敏感特性使得金刚石氮空位 (NV) 色心在量子传感领域的使用越来越广泛。为研究金刚石 在振动测磁方面的优越性, 使用集成振动模块把传统的共聚焦系统集成在PCB 板上以测试振动结果。以圆柱形永磁 体作为振动测磁的质量块, 由于外界振动的影响使永磁体与金刚石NV 色心的距离产生变化, 因此金刚石NV 色心上 的磁场强度也会产生变化。对振动效应的检测通过金刚石NV 色心上光探测磁共振 (ODMR) 荧光信号的分析来获 得。集成振动实验在距离永磁体15 mm 范围内对振动效应进行验证, 测试得到基于金刚石氮空位色心振动传感的位 移噪声灵敏度为11 nm /Hz1/2。

Abstract: The highly precise sensitivity of atoms to magnetic fields has led to the increasing application of diamond nitrogen vacancy (NV) color centers in the field of quantum sensing. To investigate the superiority of diamond in vibration magnetometry, an integrated vibration module is used to integrate a conventional confocal system on a PCB board for vibration testing. A cylindrical permanent magnet is used as the mass block for vibration magnetometry. Due to the influence of external vibrations, the distance between the permanent magnet and the diamond NV color center will change, so the magnetic field intensity on the diamond NV color center will also change. The detection of the vibration effect is obtained by analyzing the light-detected magnetic resonance (ODMR) fluorescence signal of diamond NV color core. Integrated vibration experiments are performed to validate the vibration effect at a distance of 15 mm from the permanent magnet, and the sensitivity of the displacement noise based on the vibration sensing of diamond nitrogen vacancy color core is tested to be 11 nm /Hz1/2.
