High-Speed Double-edged Wavelength Interrogation Technology for Fiber Bragg Grating
高速双边缘光纤光栅波长解调技术

High-Speed double-edged Wavelength Interrogation Technology for fiber Bragg grating sensor array was proposed,which employed the logarithm of the output ratio between the adjacent two channel of arrayed waveguide grating to determine the measured wavelength.This system permitted a fast and simultaneous interrogation of multiple wavelengths without any mechanically moving parts.The thesis mainly demonstrated the feasibility of this interrogation project in theory and experiment.
