The invention belongs to the technical field of gyroscopes and relates to a magnetic shielding method used for a magnetic
resonance gyroscope. The active-passive magnetic shielding method includes 1) a step of passive shielding, namely a step of setting a passive shielding layer at the outside of the magnetic
resonance gyroscope, with the shielding layer being a high-magnetic-permeability material, and 2) a step of
active compensation, namely a step of setting an
active compensation device inside a passive shielding device and outside a sensitive structure of the magnetic
resonance gyroscope, wherein the
active compensation device comprises an atom
magnetometer, a three-dimensional
magnetic field coil and a
current source. The technical problem to be overcome is a problem that magnetic shielding methods at present cannot meet efficient environment
magnetic field shielding requirements for small-size magnetic resonance gyroscopes. The method improves magnetic shielding performance on the base of not increasing hardware components of the magnetic resonance gyroscope.
