Superimposed long period and short period Bragg grating sensor for LRI monitoring

Résumé

We report here an optical sensor based on fiber Bragg gratings to measure strain and temperature effects simultaneously. It has been shown that Long Period Grating (LPG) and Fiber Bragg Grating (FBG) exhibit different responses to an applied solicitation, thus strain and temperature influences can be determined separately by measuring the corresponding wavelength shifts. In this paper we present a configuration based on the use of these two grating types: a LPG and a FBG written in the same fiber section, which allows us to discriminate the contributions of these two main solicitations. The sensor is embedded in a composite specimen manufactured by Liquid Resin Infusion (LRI) process for monitoring purpose.
