Nuclear Magnetic Resonance Gyro: Ultimate Parameters


The fundamental limitations for the basic metrological parameters of the nuclear magnetic resonance gyro (NMRG) are analyzed. The determinant factors limiting its sensitivity, such as atomic projection noise and light shot noise, are considered. Formulas are derived to estimate the ultimate sensitivity of the NMRG and study its dependence on the parameters of the sensitive element. The main causes of NMRG drifts and possible ways to improve its metrological characteristics are discussed.
