Fiber Bragg Grating Low-Frequency Demodulation System
A demodulation algorithm is vital for a fiber Bragg grating (FBG) sensing system. In this paper, a novel demodulation algorithm based on the variable-step-size method and cross-correlation algorithm is proposed to demodulate the wavelength of an FBG. The characteristic feature of these sensors is that the position of the spectrum changes due to the action of a particular physical quantity. Determining the wavelength shift is the most important issue in precise measurements of.
