Crosstalk investigation of FBG-based bidirectional optical crossconnects amplifiers in the presence of intraband crosstalk arises in FBG-OC-based bidirectional optical cross connects (BOXCs) for bidirectional WDM ring networks (... H Yuan,W Zhong,M Premaratne - John Wiley & Sons, Ltd 被引量: 0...
This paper presents a novel non contact radial vibration displacement measurement method based on fiber Bragg grating (FBG) sensing technology and introduces the principle and structure of the vibration sensor. The static displacement calibration experiment was carried out to determine linear range and ...
Therefore, a reflected signal from FBG is used to map the strain or temperature event. Moreover, the experimental results demonstrate the feasibility of FBG-based positioning method. Also, the positioning error is ~10 cm with spatial resolutions of 2, 5, 10, 20, 50, and 100 cm. In ...
In this work, a fiber Bragg grating (FBG)-based optical fiber accelerometer (OFA), which was designed and calibrated to operate through wavelength and optical power variations using different interrogation setups, was fixed together with a pair of FBG arrays along a 1020 carbon steel pipeline ...
