Abstract

In this paper we propose a concept for a quasi-distributed fiber-optic strainand temperature sensor based on time division multiplexing (TDM) of in-line coupledFabry-Perot interferometers (FPI) with fiber Bragg gratings used as weak reflectors. A"differential" two core fiber is used for separate measurement of strain and temperatureand a dual-wavelength technique is used to perform absolute measurements over anextended dynamic range. Some advantages and limitations of this sensor system are dis- cussed. The system has been primarily designed to be embedded in composite structuresfor aerospace applications.
