Abstract:

The effect of inertial rotation in nuclear mag netic resonance is described, and several schemes for rate gyro operation are given. A generalized expression is obtained for the directional drift of a rate or an integrating rate nuclear magnetic resonance nmr gyro due to resonance sensing error. An unavoidable source of such error is the inherent magnetic noise in a nuclear spin system, and the resulting gyro directional drift for a steady state Bloch spin system is expressed in terms of adjustable parameters temperature, field strengths, relaxation times, etc.. For conventional laboratory parameter values, the rms one-hour drift due to spin system magnetic noise is about one degree. A cursory discussion of a rapid adiabatic passage gyro is included. Author
