Superstructure Fiber Bragg Grating Sensors for Multiparameter Sensing

Hamid Alemohammad     AOMS Technologies Inc., Toronto, ON, Canada


This chapter is focused on the modeling, design, and fabrication of superstructure fiber Bragg gratings (SFBGs) for the simultaneous measurement of temperature and strain. The methodology for the development of a structural model, along with the opto-mechanical model of SFBGs, is presented. The chapter concludes with experimental results consisting of the optical response of SFBGs exposed to structural loading and temperature variations, and also, the simultaneous measurement of strain and temperature.
