Paper Abstract

The article was based on the technology and principle of DWDM, which was widely used in optical fiber communication systems, and made use of filter curve and technology of WDM into multichannel dynamic measurements. The technology of the investigation was based on the passive demodulation technologies. The samling rate of the real-time high-speed mutilchannel fiber Bragg grating monitoring system can reach 200KHz, which can both meet the needs of static and dynamic measurement and achieve the monitoring in dynamic environment. In order to adapt the requirement of static and dynamic measurement, increasing the sampling and transmission speed of the fiber grating demodulation is needed. In this article, the wavelength demodulation range of the system is about 0.7 nm, the precision can be 10~17 pm, and transmission interface is based on the USB 2.0, which speed is fast enough for the use of our monitoring system.
