Problems solved by technology

[0004] However, the measurement range of the traditional method is limited by the π phase. When the interferometric phase shift caused by the change of the rotational angular rate exceeds π, it is impossible to judge which period it is in, and there is an ambiguity problem, so the dynamic range of the measurement is small.

Abstract

The invention relates to an atomic interference gyroscope signal resolving method and device, computer equipment and a storage medium, and is suitable for the technical field of precise instruments, and the method comprises the steps: carrying out the frequency modulation of coherent control laser, and obtaining modulated laser; carrying out coherent manipulation on an atomic beam by utilizing the modulated coherent manipulation laser, so that the atomic beam interferes with each other; obtaining interference fringes formed after interference of the atomic beam, and calculating an envelope center point of the interference fringes; and calculating the rotation angular rate based on the modulation frequency corresponding to the envelope center point. By adopting the method, the rotation angular rate of the atomic interference gyroscope can be accurately and effectively calculated, and the measurement in a large dynamic range can be achieved.

Description

technical field [0001] The present application relates to the technical field of precision instruments, in particular to an atomic interference gyroscope signal resolution method, device, computer equipment and storage medium. Background technique [0002] As a high-sensitivity inertial sensor, the atomic interferometer can accurately measure important physical quantities such as gravitational acceleration, gravitational constant, and rotational angular velocity. The atomic interference gyroscope is a quantum sensing device that precisely measures the angular rate of rotation. High-precision atomic interference gyroscopes have broad application prospects in the fields of inertial navigation, land survey, and basic physics research. Therefore, the development of atomic interference gyroscopes has scientific significance and practical value. [0003] Lasers are usually used to coherently manipulate atoms, causing them to split, reflect, and combine beams. After the beam is c...
