Abstract
One embodiment of the invention includes an atom beam gyroscope system. The system includes an atom beam system that generates an atom beam comprising alkali metal atoms along a length of a detection region orthogonal to a sensitive axis. The system also includes a detection system comprising a detection laser and photodetector. The detection laser can generate an optical detection beam that illuminates the detection region to pump the alkali metal atoms. The photodetector can measure an optical absorption of the optical detection beam by the alkali metal atoms in the atom beam and to generate an intensity signal associated with the measured optical absorption. The system further includes a gyroscope sensor configured to calculate rotation of the atom beam gyroscope system about the sensitive axis based on a magnitude of the intensity signal due to a Doppler-shift in energy of the alkali metal atoms in the atom beam.
