    • Systems and methods for performing vibration error suppression in a fiber optic gyro sensor. An example system includes a light source, a sensing loop assembly, a photo detector, and a processing component. The light source generates a light signal that is then modulated by the sensing loop assembly and applied to a fiber optic coil in the assembly. The photo detector receives a modulated light signal that is an output of the sensing loop assembly (coil) and generates an analog signal. The processing component converts the generated analog signal into a modulated digital signal, determines an average of the modulated digital signal, determines an intensity modulation amplitude based on the determined average of the modulated digital signal, and re-scales the modulated digital phase signal based on the determined intensity modulation amplitude.

    • A phase jump amplitude and timing controller is used in a fiber optic gyroscope for suppressing color noise. The phase jump amplitude and timing controller inserts a phase/voltage jump into the feedback signal of the loop closure electronics of the fiber optic gyroscope. This phase/voltage jump breaks the repeated pattern of the drive signal. The IOC time-dependent characteristics are totally eliminated by the randomized feedback signal because no repeated signal is applied to the IOC. The randomized amplitude is preferably within the full ±π phase such that the optical errors average to zero. A fixed frequency higher than the interested spectral region can shift the color noise to higher frequency. A randomized frequency can spread the color noise over full spectrum, and totally eliminate the RDS. In other words, the color noise caused by the nonlinearity of the driving circuit and IOC spreads out over a wide range of spectrum such that no distinct frequency peaks are apparent in the spectral domain.
    • 在光纤陀螺仪中使用相位跳变幅度和定时控制器来抑制彩色噪声。 相位跳变幅度和时序控制器将相位/电压跳变插入到光纤陀螺仪的闭环电路的反馈信号中。 该相位/电压跳转会中断驱动信号的重复模式。 随机反馈信号完全消除了IOC时间依赖特性,因为没有重复的信号被应用于IOC。 随机振幅优选在完全±π相位之内,使得光学误差平均为零。 高于感兴趣的光谱区域的固定频率可以将颜色噪声移位到更高的频率。 随机频率可以在全频谱上传播颜色噪声,完全消除RDS。 换句话说,由驱动电路和IOC的非线性引起的颜色噪声在宽范围的频谱上扩展,使得在频谱域中没有明显的频率峰值。
