摘要:

克服死区是闭环光纤陀螺设计中需要考虑的重要问题。运用适当的小角速度测试方法测得了闭环光纤陀螺输出信号中的死区。采用了一种简便的偏置输出相移信号的方法以克服闭环光纤陀螺输出信号中的死区。实验表明,上述方法可以克服死区。

Abstract:

The compensation of Dead Band is an important problem in designing a closed loop Fiber Optic Gyroscope. The author measured Dead Band in the output signal of the closed loop FOG by the measuring method of small rotation rate and adopted a convenient method of biasing the output phase shift of closed loop FOG to compensate Dead Band. Some important problems concerning how to implement the above method have been discussed.

Key words: fiber optic gyroscpe, fiber optic sensor, electric coupling
