Propuesta de un transductor para la medida simultánea de strain y temperatura basado en una combinación de una red de difracción de periodo largo y una cavidad Fabry-Perot

Abstract

Long period fiber optic gratings written in single mode optical fibers are becoming a very powerful technique for the construction of structural monitoring transducers. We propose a new transducer with optimal characteristics in this field. The structure of the transducer is designed using two semireflective splices forming a Fabry-perot cavity with a long period fiber grating that can be used to obtain simultaneous measurement of strain and temperature.
