Abstract

We present a mobile 3D accelerometer based on matter-wave interferometry, which is capable of measuring three orthogonal accelerations, each with respect to an independent inertial reference frame defined by the surface of a mirror. On each axis, we construct a hybrid quantum/classical accelerometer by using correlations between the atoms and a mechanical accelerometer attached to the back of each reference mirror. This system combines the large bandwidth and dynamic range of classical devices with the high sensitivity and accuracy of atom interferometers. By correcting each classical accelerometer independently, we are able to track the full acceleration vector with high accuracy.
