低成本光纤陀螺零相交信号处理

LOW COST SIGNAL PROCESSING SCHEME USING ZERO CROSSING FOR THE FIBER OPTICAL GYRO

介绍光纤陀螺的低成本信号处理方案。此方案利用光纤陀螺输出信号的过零特性，把位相检测过渡为时域信号检测。

This paper discribes a low cost signal processing scheme for the fiber optical gyro. The key to this scheme is to use the zero crossing for output signal of fiber optical gyro.
