Desarrollo de una red de sensores de fibra óptica para la detección de humedad mediante reflectometría óptica

Abstract

A method to detect humidity is presented. It is based on a reflective fibre optic sensor. Volume changes due to water presence in a hydrogel compound are transformed into variations of the light coupled into a monomode optical fibre by a reflective device. This kind of sensors is easily arranged in the form of a linear array so they can be monitored with an OTDR. An experimental example of such a network in presented.
