摘要 本文提出了一种基于分布式反馈光纤激光器（DFB-FL）和数字相位生成载波（PGC）解调的振动传感器系统。 DFB-FL采集外部声音信号，然后将信号采集到计算机中进行处理。该系统的传感不需要电源，因此系统可以应对突发灾难。此外，该系统还可用于远程预警。
Abstract A vibration sensor system based on Distributed Feedback Fiber Lasers (DFB-FL) and digital Phase Generated Carrier (PGC) demodulation is presented in this paper. The external sound signals is collected by DFB-FL, and then the signal is gathered into the computer and is processed. The sensing of the system need no power supply, so the system can deal with unexpected disasters. Moreover, the system can be used for remote warning.
