Paper Abstract

A novel laser based corrosion sensor is being developed using embedded optical fibers, near- infrared (NIR) dyes and phase resolved fluorescence spectroscopy (PRFS) to detect corrosion by-products at the incipient stage. During the initial research effort, the practicality of using PRFS and NIR dye fluorescence lifetimes for characterization of metal ions was demonstrated. We have also demonstrated fiber optic strain measuring technology which will be integrated into the sensor design. The sensor will, thus, provide both early warning of corrosion as well as structural strain information.
