摘　　要：波长检测技术是当前光纤光栅传感领域的重点和难点之一,光纤光栅传感系统的一个显著优点是易构成分布式传感网络系统,实现多点、多区域同时检测。文章以几个典型的解调系统为例,重点分析了分布式光纤光栅传感系统中信号解调的工作原理、特点和性能。Techniques of wavelength detection is one of the critical and difficult problem in nowadays FBG sensoring technique fields. A big advantage for the FBG sensoring system is easy to form the distributed sensing network system, and achieve the multi-point and multi-field detection at the same time. This paper provides several typical examples. The principle of operation, characteristics and functions of signal demodulation are discussed in distributed fiber Bragg grating sensor system.
