    • A system for measuring strain includes an optical fiber having a central portion secured between two fixed points. A first light source outputs light at a first frequency and a second light source outputs light at a second different frequency. The two light sources are both coupled to a first end of the optical fiber. A back scatter detector is also coupled to the first end to receive a return light signal from the optical fiber and outputs a signal based thereon. A forward scatter detector is coupled to a second end of the optical fiber to receive a forward light signal from the optical fiber and outputs a signal based thereon. A processor receives the signals from the back scatter detector and the forward scatter detector and generates an output signal proportional to the strain between the two fixed points based on the received signals.
    • 用于测量应变的系统包括具有固定在两个固定点之间的中心部分的光纤。 第一光源以第一频率输出光,而第二光源以第二不同频率输出光。 两个光源都耦合到光纤的第一端。 背散射检测器还耦合到第一端以从光纤接收返回光信号并基于其输出信号。 前向散射检测器耦合到光纤的第二端以从光纤接收正向光信号并基于该信号输出信号。 处理器从后向散射检测器和前向散射检测器接收信号,并且基于接收的信号产生与两个固定点之间的应变成比例的输出信号。
