摘要：

In this paper, the tilted fiber Bragg grating is proposed as a corrosion sensor and experimentally demonstrated for measuring and evaluating corrosion of steel rebars in wet conditions. To expedite the corrosion process, the impressed current technique was used to achieve a 28.9% mass loss in the rebar for a total time of 24 h. It is observed that the cladding resonant wavelengths red-shift during the corrosion process and the wavelength shifts are greater for higher order resonances. The proposed technique can be used for monitoring steel corrosion.
