Abstract
One embodiment of the invention includes an atomic sensing system. The system includes an atomic sensing device configured to generate an output signal along an output axis in response to a plurality of control parameters. The system also includes a signal generator configured to apply a reference signal to a cross-axis that is approximately orthogonal to the output axis. The system also includes a phase measurement system configured to demodulate the output signal relative to the reference signal to measure a relative phase alignment between the output axis and a physical axis of the atomic sensing device based on the reference signal.
