Nuclear magnetic resonance gyroscope with discrete working media

Abstract

The invention relates to a nuclear magnetic resonance gyroscope with discrete working media, which adopts a form that three air chambers are closely connected in parallel, so that two processes of atomic polarization precession and atomic precession magnetic moment detection are independent, and high-precision precession magnetic moment detection in a specific direction is easy to achieve withoutbeing interfered by a driving magnetic field. The depolarization effect of detection linearly polarized light on atoms does not need to be considered, and the gas component filling of each atom gas chamber only needs to consider the single effect of the gas chamber, so that the gas component is easy to optimize; the types of filling gases are few, and the requirements on the atomic gas chamber filling process 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, which 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, which is mainly used to measure the rotation rate and angle of objects. Since its birth, mechanical rotor gyroscopes, optical gyroscopes, and MEMS gyroscopes have appeared successively. 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: the interference type based on the Sagnac effect and the spin type using atomic electron spin in...

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.
