Cold-Atom Gyroscope

Rotation sensor built on matter-wave interference: atomic interferometer gyroscopes (AIG) and atomic spin gyroscopes (ASG) for navigation.

Specifications & Metrics

Atomic interferometer gyroscopes (AIG) sense rotation with atom interferometry, while atomic spin gyroscopes (ASG) use atomic spin.
Both offer compact size, high precision, and the possibility of being made on a chip scale for inertial navigation.
Chu's 1991 atom interferometer is tabulated with a Sagnac rotation sensitivity of 0.3 rad/s/√Hz.
