Abstract

The paper presents a method that can be used to measure metal corrosions based on the evanescent field of a fiber, and a pair of fiber Bragg gratings between the transducer is utilized for multiplexing. The technique is based on the ratio of the reflecting intensities from the reference and the sensing fiber Bragg gratings. The ratio has been found to be independent of optical intensity variations.
