Cold Atomic Gravimeter

The A-Grav cold atom gravimeter is a quantum precision measurement product developed by Guodun Quantum with completely independent intellectual property rights. It uses freely falling cold atomic clusters in an ultra-high vacuum environment as a test mass, and uses laser precision to control the splitting, state reversal, and merging of cold atomic matter waves, thereby forming cold atomic matter wave interference. Finally, the gravity acceleration value is obtained by measuring the phase shift of the matter wave, making it a new type of absolute gravimeter. A-Grav consists of two main parts: a detection unit and a control unit. The detection unit is used to sense gravitational acceleration, while the control unit is used to provide the necessary optoelectronic, timing modules, data processing, and output functions for gravity measurement. This product can work continuously without interruption and is suitable for various scenarios from fixed-point measurement to mobile exploration. It can be widely used in geological hazard monitoring, geodetic surveying, resource exploration, buried object detection, gravity assisted navigation and other fields.
