A novel structurally simple and easily fabricated FBG water level sensor was developed.Three-dimensional FEM was adopted to optimize the structural pattern and specifications of sensor,and linear optical-mechanical transformation relationship between FBG central reflection wavelength and water level was obtained.The sensor model was fabricated and tested,and its experimental results of optical-mechanical transformation relationship agree well with the theoretical formulation.
