Abstract
Compact inertial measurement systems and methods based on atom interferometry. Certain examples provide a combination atomic accelerometer-gyroscope configured to recapture and cycle atom samples through atom interferometers arranged to allow the next measurement to use the atoms from the previous measurement. Examples of the apparatus provide inertial measurements indicative of rotation for different inertial axes by applying atom interferometry to a plurality of atom samples launched in opposite directions to allow for measurement of both acceleration and rotation rates. In some examples, the inertial measurement apparatus provide a combined atomic gyroscope and an atomic accelerometer in a compact six Degrees of Freedom (6 DOF) IMU.
