Abstract
A fluoride sensor includes an aluminum layer situated on a distal end face of an optical fiber. A light source directs light into the optical fiber at a proximal end and reflected light from the aluminum layer at the distal end face is directed by the fiber to a detector. A rate of change of a detector signal is processed to produce an estimate of a concentration of fluoride.
