Abstract

Atom interferometers are an exquisite measurement tool for inertial forces. However, they are commonly limited to one single sensitive axis, allowing high-precision multi-dimensional sensing only through subsequent or postcorrected measurements. Here, we introduce a novel 2D-array-arrangement of Bose-Einstein Condensates (BEC) initialized utilizing time-averaged optical potentials for simultaneous multi-axis inertial sensing. Deploying a 3 x 3 BEC array covering 1.6 mm^2, we perform measurements of angular velocity and acceleration of a rotating reference mirror, as well as a linear acceleration, e.g., induced by gravity, gradients, and higher order derivatives. We anticipate increased sensitivity of our method in interferometers with large scale factors in long-baseline or satellite atom interferometry. Our work paves the way for simple high-precision multi-axis inertial sensing and we envision further applications, e.g., for three-dimensional wave front characterization.
