摘要： A cell in one example comprises an alkali metal and a coating of parylene on an interior surface of the cell. In one implementation, the alkali metal may be an optically pumped gaseous phase of an alkali metal. The parylene coating minimizes interaction of the excited state of the alkali metal, increases lifetime of the excited state, and minimizes interaction of nuclear spin states with the cell walls.

摘要： The intensity and frequency variation due to retroscatter in a ring laser gyroscope are determined and used to correct the gyro scale factor. The orthogonal types of scatter due to dielectric variation and due to height variation, which lead to common mode phase delays of 0 and .pi./2 respectively are taken into account in calculating the correction to the scale factor. The scale factor errors are determined in terms of observable quantities. Scale factor error control is accomplished by extracting a portion of both of the two counterpropagating light beams and measuring their respective intensities, creating intensity modulation indices representative of the sum and difference intensities, using closed loop control of the real-time difference between the intensities of the beam in the ring laser gyro to reduce scale factor variation using push-pull mirror control of at least two mirrors. The residual error after push-pull mirror control minimization is output for use by a navigation system computer.

摘要： An apparatus in one example comprises a polarization filter and a polarization analyzer. The polarization filter comprises a first polarization axis. The polarization analyzer comprises a second polarization axis. The polarization filter is configured to polarize detection light for a nuclear magnetic resonance (NMR) cell along the first polarization axis. The polarization analyzer is configured to receive the detection light from the NMR cell and pass a portion of the detection light to a processor for determination of angular rate information. The portion of the detection light passed to the processor is based on an orientation of the second polarization axis relative to the first polarization axis. The orientation is selected to maximize a signal-to-noise ratio of the detection light.
