| Abstract: | The quantum sensor based on the cold atom interferometer has a high theoretical accuracy and is widely used in various fields of natural science, especially in the field of gravity measurement and inertial sensor. In this paper, the basic principle of atom interferometer is firstly introduced. On this basis, the interference phase of a pulsed Mach-Zehnder interferometer based on two-photon stimulated Raman transition is given. Then, the application and development course of atom interferometer in gravimeter and gyroscope are described. The development course and trend of the most mature atom gravimeter are analyzed emphatically. At last, the development direction of the atom interferometer in application is pointed out. |
