Nuclear magnetic resonance gyroscopes

Definition

Nuclear magnetic resonance (NMR) gyroscopes are precision devices that use the principles of nuclear magnetic resonance to measure angular rotation. By detecting the precession of nuclei in a magnetic field, these gyroscopes can provide highly accurate orientation data without the need for moving parts. This technology is significant because it combines the stability of gyroscopic motion with the sensitivity of nuclear magnetic resonance, making it suitable for applications in navigation and stabilization.
