Description

technical field [0001] The invention relates to solid-state diamond NV color center non-exchange quantum geometric phase detection, in particular to a nuclear magnetic resonance atomic gyroscope. Background technique [0002] The atomic gyroscope is a new technology developed in recent years. It mainly uses laser pumping to polarize the target electrons to sense the rotation of the external carrier (spin polarization). The gyroscope made by relying on the target atomic spin has the advantages of small size and high sensitivity, which is a new direction for the development of gyroscope technology in the future. The development of nuclear magnetic resonance gyroscopes (NMRG) in various countries in the world mainly includes two directions: room temperature optically pumped NMRG and low temperature superconducting NMRG. Room temperature optically pumped NMRG began to conduct in-depth research as early as 1960 in the United States, developed key technologies such as working med...
