摘要: Abstract Unlike usual spectral analysis of the fiber Bragg grating (FBG) sensors, a novel weak pressure sensor based on Stokes parameter FBG is proposed in this paper. The evolution first normalized s1 with respect to studied theoretically and experimentally. A theoretical model for sensing by use built numerically simulation also carried out. dual-wavelength analytical method reduce influence wavelength drift improve measurement accuracy. Under conditions 0–5 N, experimental sensitivity 0.0754/N. Good agreements between experiment results numerical simulations verify feasibility method.
