A kind of nuclear magnetic resonance gyroscope with discrete working medium

Abstract

The invention relates to a nuclear magnetic resonance gyroscope with a separate working medium. The nuclear magnetic resonance gyroscope adopts the form of three air chambers that are closely connected in parallel, so that the two processes of atomic polarization precession and atomic precession magnetic moment detection are independent, and it is easy to realize a specific direction. The high-precision precession magnetic moment detection is not disturbed by the driving magnetic field, and there is no need to consider the depolarization effect of the detection linearly polarized light on the atoms. The gas component filling of each atomic gas chamber only needs to consider the single effect of the gas chamber, which is easy to optimize. Gas composition; there are fewer types of filling gases, and the requirements for the filling process of atomic gas chambers are reduced.

Description

technical field [0001] The invention relates to the field of nuclear magnetic resonance gyroscopes, in particular to a nuclear magnetic resonance gyroscope with independent nuclear polarization and detection process space, has the characteristics of miniaturization, high precision and strong reliability, and can be applied to the navigation of strategic and tactical weapons and equipment Guidance and Control. Background technique [0002] Gyroscope is the core device of inertial navigation, mainly used to measure the rotation rate and angle of objects. Since its birth, there have been mechanical rotor gyroscopes, optical gyroscopes and MEMS gyroscopes. As a new type of gyroscope, atomic gyroscopes are expected to become the next generation of high-precision gyroscopes. According to the working principle, atomic gyroscopes can be divided into two types: interference type based on Sagnac effect and spin type using atomic electron spin information. At present, the most mature ...

Problems solved by technology

In the above conventional scheme, since the alkali metal atoms are used to polarize the inert gas atoms, its steady-state polarizability drops significantly, which greatly affects its magnetic detection accuracy as a magnetometer medium

At the same time, the instrument accuracy of the above scheme strongly depends on the accurate filling of the distribution ratio of three or more gas components in the atomic gas chamber. The process is difficult and the production consistency is poor. The overall scheme needs to be further improved.
