Abstract
Disclosed is a multi-axis atom interferometer system, including a source of cold atoms, a laser source generating a first light pulse configured in such a way as to spatially split the source of cold atoms into a first cloud of atoms propagating along a first trajectory along a first axis and a second cloud of atoms propagating along a second trajectory along a second axis, a second light pulse adapted to spatially deflect the first trajectory along the second axis and simultaneously the second trajectory along the first axis towards a first point and a last light pulse adapted to recombine the at least one part of the first cloud of atoms and the at least one part of the second cloud of atoms at the first point, and a detection system measuring an interferometric phase-shift accumulated between the first light pulse and the last light pulse.
