    • The location of a physical disturbance along an optical waveguide is determined by measuring different propagation times for the resulting phase variation to propagate to phase responsive receivers at ends of bidirectional signal paths. Each receiver can have a coupler that functions as a beam combiner and as a beam splitter inserting the opposite signal. On each receiving end, the coupler provides one or more detectors with signals from which phase related independent variable values are taken, processed and mapped to phase angles. Relative phase angle versus time is derived for each opposite signal pair and correlated at a time difference, i.e., a difference in propagation time from which the location of the disturbance is resolved. Polarization sensitive and polarization insensitive examples are discussed with various optical fiber arrangements.
    • 沿着光波导的物理扰动的位置通过测量所得到的相位变化的不同传播时间来确定,以在双向信号路径的端部传播到相位响应接收机。 每个接收机可以具有用作波束组合器的耦合器和用于插入相反信号的分束器。 在每个接收端,耦合器向一个或多个检测器提供信号,从相位相关的独立变量值被采取,处理并映射到相位角。 对于每个相对的信号对导出相对相位角对时间,并且在时间差处相关,即,扰乱位置从该差异被解析的传播时间差。 与各种光纤布置讨论偏振敏感和极化不敏感的示例。
