光纤陀螺是基于效应工作的角速率传感器，具有全固态、体积小、
质量轻、动态范围宽、启动快、成本低、易集成等突出特点，在军事和民用领
域备受世界各国关注，获得了广泛应用。然而，受元器件性能、寄生效应和周
围环境的影响，光纤陀螺的输出易产生漂移，影响惯性导航系统的精度。因此，
抑制光纤陀螺漂移误差，提高其测量精度具有重要意义。(Fiber optic gyroscope(FOG) is a kind of angular rate sensor based on Sagnac
erect with solid state, small size, light weight, wide dynamic range, fast starting,
low cost, high reliability and so on. Many countries pay much attention to FOG for
the military and civilian purposes. FOG is widely used in the world because of its
outstanding features. However, FOG is easily affected by the performance of its
components, parasitic effects and the surroundings. This leads to the FOG output
drift and deteriorates the precision of the inertial navigation system. Therefore, it is
significantly important to suppress the FOG drift error to improve the FOG
measurement accuracy.)
