| Abstract: | As a novel quantum sense tool, Micro nuclear magnetic resonance gyro has been developing for the goal of engineering and integration. The micro NMRG has the characteristics of high precision, little volume, low consumption, high dynamics, and un-vibration. It can be used for the navigation and control of weapons. This paper expatiates the principle for NMRG, and then discusses several schemes, such as the close-loop scheme, open-loop scheme, and low-temperature superconducting scheme. We have also analyzed the key technologies of NMRG, such as micro atomic cell, magnetic coils, and non-magnetic heating. At last, we forecast the perspective and tendency of NMRG. |
