  • Patent number: 12516937
    Abstract: An inertial sensor includes a dual atom interferometer. A moving standing light wave generation device in the dual atom interferometer generates M (3?M) moving standing light waves. Each of the M moving standing light waves is generated by a pair of counter-propagating laser beams. The moving standing light wave generation device adjusts two-photon detuning of a pair of counter-propagating laser beams corresponding to each of N (2?N<M) moving standing light waves out of the M moving standing light waves such that the difference between an interferometric phase corresponding to one atomic beam obtained by interfering with the M moving standing light waves and an interferometric phase corresponding to the other atomic beam obtained by interfering with the M moving standing light waves stays constant.
