英文摘要： In order to solve the low sensitivity, larger drift (MEMS gyroscope), larger volumes and longer start-up (nuclear magnetic resonance gyroscope), we proposed a novel method of solid-state spin angular velocity measurement based on nitrogen-vacancy (NV) centers in diamond with multidisciplinary technologies. In this method, we will refine the theory of angular rate detection with high density NV centers in diamond, and setup the measuring system for external angular rate variation by solid spin control in assemble of NV centers. We also make this system has the ability of angular rate detection by exploiting photon excitation, manipulation and detection techniques using optical method. Further, we need to improve efficiency and reduce the noise of photon excitement and collection to improve the sensitivity of the system. All these will be the basis for practice of gyro in the future. In conclusion, this project can shed light on the next generation of atomic navigation, atomic clock, atomic magnetic sensing and even on spintronic devices theoretically and experimentally.
