摘要
介绍了几种典型解调方法的特点,提出了一种高精度、大容量、可扩展的光纤光栅传感解调方法。该方法用扫描激光器作为光源提高信噪比,用FPGA电路进行并行采集实现大容量,用F-P标准具提供实时波长校准,适用于各种大型结构体长期实时健康安全监测。
The characteristics of several typical demodulation methods are introduced respectively.A highpre cious largecapacity FBG sensing demodulation system is proposed, it uses the swept laser, uses FPGA to de sign the drive circuit and signal processing circuit, and uses FP etalon.Suitable for the longterm realtime monitoring of various largescale structure.
