Abstract
By combining wavelength division multiplexing(WDM) and spatial division multiplexing(SDM), the number of fiber Bragg grating(FBG) sensor demodulation wavelength can be increased. The fiber Bragg grating sensor detection system that is between FBG sensor detector and computer systems is developed. By serial bus, the system can communicate respectively with optical switches and demodulator, achieve the real-time rendering of sensing spectrum and dynamic update FBG sensing center wavelength of 16 channels. Test results show that system work wavelength range is 1527~1566nm, center wavelength resolution is 1pm, and the wavelength collected time is 620ms.
