Abstract
One embodiment includes an accelerometer system. The accelerometer system can include a Far-Off Resonance Trap (FORT) control system configured to generate an optical trapping beam. The system can also include a FORT accelerometer detection system including a FORT that is configured to trap a cluster of atoms based on the optical trapping beam. The FORT accelerometer detection system can also include an interrogation system configured to determine motion of the cluster of atoms along at least one axis resulting from an external acceleration in the at least one axis based on a relative phase shift of an optical probe beam through the cluster of atoms. The system can further include an acceleration processor configured to calculate the external acceleration in the at least one axis based on the relative phase shift of the optical probe beam.
