Miniature Atomic Gyroscopes
Miniature atomic gyroscopes (MAG) or nuclear magnetic resonance gyroscopes (NMRG) employ noble-gas nuclear spins as high-coherence rotation sensors. Advanced prototypes exist but application remains confined to laboratory environments. The primary challenges for MAGs are the long relaxation times that give nuclear-spin devices exquisite long-term stabilities but also lead to narrow resonances that limit the gyroscope operational bandwidth.
Objective: in macQsimal, partners will work closely together to develop, fabricate and test a Compact Atomic Gyroscope demonstrator based on spin-exchange optical pumping (SEOP) in a MEMS cell for target applications in the automotive industry.
