    • A spatially distributed sensor system (100) has an optical transmitter (102), an optical conduit (104) optically coupled to the optical transmitter (102) at an input position, and a sensing element (106) optically coupled to the optical conduit (104) at a position along th optical conduit (104) spatially separated from the input position. The sensing element (106) is structured to split off a fraction of light from the optical transmitter (102) upon being coupled into the optical conduit (104) and to return light to the optical conduit (104) in amount responsive to an effect being sensed. The spatially distributed sensor system (100) also has an optical receiver (108) coupled t the optical conduit (104) to receive at least a portion of light from the optical conduit (104) that includes light returned to the optical conduit (104) from the sensing element (106). An analysis of light received by the optical receiver (108) provides information to determine a position of the sensing element (106).
    • 空间分布式传感器系统(100)具有光学发射器(102),在输入位置处光耦合到光发射器(102)的光学导管(104)和光学耦合到光导管(106)的感测元件(106) 104)沿着与输入位置空间分离的光导管(104)的位置。 感测元件(106)被构造成在被耦合到光导管(104)中时从光发射器(102)中分离出一部分光,并且响应于效果而将光返回到光导管(104) 检测。 空间分布式传感器系统(100)还具有耦合到光导管(104)的光接收器(108),以接收来自光导管(104)的至少一部分光,其包括返回到光导管(104)的光, 从传感元件(106)。 由光接收器(108)接收的光的分析提供用于确定感测元件(106)的位置的信息。
