提出了一种基于超弱光纤布拉格光栅（FBG）的串行时分复用传感器网络。12个超弱光纤光栅的空间分辨率约为0.2米区分，和他们的光谱分辨率约为10 pm的精度。光栅的低串扰使得可以沿单根光纤复用沿着超过1000个光栅。
We propose a serial time-division-multiplexing sensor network based on ultraweak fiber Bragg gratings (FBGs). Twelve ultraweak FBGs are distinguished with a spatial resolution of about 0.2 m, and their spectra are resolved with an accuracy of about 10 pm. The low crosstalk of the gratings makes it possible to multiplex over 1000 gratings along a single optical fiber.
