Scalable Multi-Loop Cold Atom Rotation Sensor

Kurzfassung

Matter-wave interferometry with cold atoms offers a competitive tool for absolute measurements of acceleration and rotation. The sensitivity of atom-interferometric gyroscopes depends on the area enclosed by the interferometer. In this contribution, we present a concept for a rotation sensor, utilizing a multi-loop interferometer geometry to achieve a scalable area while maintaining a compact setup. It enables rotation measurements of a single axis on ground and can be extended to measure rotations along all three spatial axes in microgravity, for potential applications in space missions, Earth observation, and navigation systems.
