摘要

System and method for measuring a perturbation with slow optical fiber Bragg grating sensor. How to configure an optical device, an optical device, and is provided a method of using a fiber Bragg grating. Optical device, the fiber Bragg grating, the narrowband light source and at least one photodetector. Fiber Bragg grating as a function of the wavelength, and has a power transmission spectrum with one or more resonance peaks, each of the resonance peak, and a two areas local maximum value and the slope is not zero, which there is a local maximum value between the two regions. Light generated by the narrowband light source has a wavelength in the region the inclination of the resonance peaks is one or more of the following quantities to be evaluated at the resonance peak is selected to be the maximum value is not zero. That is, the product of (a) and the group delay spectrum and a power transmission spectrum, and is the product of the minus the power reflected from the spectrum (b) the group delay spectrum and 1.
