Research Progress and the Key Technology of SERF Gyroscope

SERF gyroscope utilizes spin of electron to detect the rotation information of system in the inertial space. It can be super sensitive with small size, which has been a research focus in inertial technology. This paper introduces the basic principle of SERF gyroscope and the history of its development at domestic and oversea. The key technologies, reducing the spin relaxation effect of the atomic cell, closed loop of the nuclear spin magnetic field compensation, high sensitive signal detection, are pointed out. We also outlooks the potential applications of the SERF in future.
