| Abstract: | The gravitational field of the earth reflects the distribution of matter in the earth and its changes over time and space. The precision measurement of the gravitational acceleration can be widely used in the field of geophysics, resource exploration, seismic study, gravity survey, inertial navigation and so on. The cold atom gravimeter is a new kind of quantum sensor which has been developed rapidly in the last two decades. It utilizes the technologies of laser cooling, atom interference to realize the measurement of gravitational acceleration with high precision and sensitivity. In this paper, the development history, current situation and tread of cold atom gravimeter are introduced. The principle, classification, experimental apparatus and experimental procedures are discussed in detail. The key technologies of the portable cold atom gravimeter are analyzed. |
