Abstract:
Systems and methods for eliminating multi-path errors from atomic inertial sensors are provided. In certain embodiments, a system for performing atom interferometry includes a vacuum cell containing multiple atoms and a first plurality of lasers configured to trap the atoms within the vacuum cell. The system further includes a second plurality of lasers configured to impart momentum to the atoms and direct the atoms down multiple paths, wherein a primary path in the multiple paths has a first and second component that converge at a converging point, wherein a diverging part of the primary path in which the first and second components are diverging is asymmetrical with respect to a converging part of the primary path in which the first and second components are converging, such that only the first and second components converge at the converging point wherein other paths do not converge at the converging point.
