| Abstract: | A fiber Bragg grating (FBG) demodulation system based on the edge filter is introduced, it uses several optical components, including broadband light source, isolator, beam splitter, FBG, coupler and edge filter to collect the change light signals. At the same time, a photoelectric detector is designed to complete the photoelectric signal conversion, and NI USB-6361 is adopted for the data acquisition and analog-to-digital conversion. The measured value is obtained by Labview. |
