Research Progress and Application Analysis of the Practical Application for Cold Atom Interference Gyroscope
High-precision rotation measurements have important scientific prospects and application values in preci-sion measurement fields such as studies of fundamental physics,geophysics and inertial navigation.Based on matter wave interference and Sagnac effect,atom-interferometer gyroscopes can be built to measure the high-precision rotation rate with benefits of high sensitivity,good long-term stability and no mechanical wear.In this paper,at beginning of the basic princi-ple of atom-interferometer gyroscope,the current research status and its progress of atom-interferometer gyroscope are intro-duced,as well as the preliminary applications of atom-interferometer gyroscopes in precision measurements such as inertial navigation,earth rotation and seismic rotational waves,and general relativity test are analyzed.Finally,the limitations and possible solution methods of atom-interferometer gyroscopes in precision measurements are discussed,and the application prospects are summarized and looked forward.
