干涉型光纤传感器随机相位漂移统计特性研究

Statistical Characteristics of Random Phase Drift in the Fiber-Optic Interferimetric Sensor

提出描述干涉型光纤传感器随机相位漂移Δφ（ｔ）物理模型，给出了Δφ（ｔ）的自相关函数和功率谱密度函数，还给出了随机相位漂移周期的统计分布．

In this paper a physical model describing random phase drift of the fiber-optic interferometric sensor is presented. The autocorrelation function and the density function of POwer spectrum for the random phase drift are derived. The statistical distribution for drift period of the random phase in given.
