High accuracy inertial measurement based on atom interferometer
Zhao Chang-shan
The atom interferometer was reviewed and its recent development and progress were reported.The interferometer,based on the theory of laser cooling,trapping and manipulation of atom,utilizes the atomic particles as free fall test masses to measure the experienced inertial force of the apparatus.Many tests show that the novel inertial sensors can measure the rotation and acceleration of apparatus with unprecedented sensitivity and precision,and distinguish them by counter-propagating beams of atoms.The atom interferometer can get extensive application in inertial measurement based on them due to its compactness and long-term stability.
