Project: Studies of precision measurements of inertial rotation via three-axis NMR gyroscopes based on spinning sidebands from nuclear-quadrupole resonanceChief Specialist: Jun Luo  

Abstract: It is hard to achieve high precision gyroscopes and suppression of noises in miniature physical systems. In order to meet performance expectations for high precision, miniature size, low power and low cost in inertial navigation, we should first experimentally investigate collision frequency shifts between quadrupole nuclei and inner walls of cells, and relaxation mechanisms. Second, we are to study collision frequency shifts between quadrupole nuclei and alkali-metal atoms, and methods for common-mode suppression of collision frequency shifts.Third, we are to study and to experimentally realize new multiaxis micro-nuclear magnetic resonance gyroscopes with high precision based on spinning sidebands from many species of common-mode nuclear-quadrupole resonance spectra. Finally, we are to develop new multiaxis micro-nuclear magnetic resonance gyroscopes with the navigation grade, and to measure inertial rotation. Therefore, these research results will be important for developing new multiaxis micro-nuclear magnetic resonance gyroscopes with high precision.
