    • A fiber optic gyroscope (FOG) includes a sensing coil with a particular magnetic sensitivity magnitude and direction with respect to the geometric axis of the sensing coil. The FOG also includes a plurality of magnetic compensators. Each magnetic compensator is fabricated so as to have a particular magnetic sensitivity magnitude and direction, the magnitude being comparable to that of the sensing coil, with large tolerances relative to the magnitude and direction. The compensators are positioned relative to one another and to the sensing coil such that the combined magnetic sensitivities of the compensators cancel the magnetic sensitivity of the sensing coil.
    • 光纤陀螺仪(FOG)包括具有相对于感测线圈的几何轴线的特定磁敏度幅度和方向的感测线圈。 FOG还包括多个磁补偿器。 每个磁补偿器被制造成具有特定的磁敏度幅度和方向,该幅度与感测线圈的幅度相当,具有相对于幅度和方向的大公差。 补偿器相对于彼此和感测线圈定位,使得补偿器的组合磁敏度抵消感测线圈的磁敏感度。
