Abstract

A fiber grating corrosion sensor system which includes fiber grating corrosion and/or chemical sensors formed by writing one or more fiber gratings that are transverse load sensitive so that when corrosion occurs to a transverse stress applying sleeve there over, the transverse loading is relieved. The spectral signals from the fiber grating sensors change with variations in transverse strain providing a measurement of the degree of corrosion or change in chemical content.
