Abstract

The influence of the lamination process on stress sensitivities of the composite structure incorporating optical fiber sensors with fiber Bragg gratings (FBGs) and polarimetric highly birefringent (HB) fibers has been investigated. Coating layers of the HB fibers are found to be responsible for performance of the embedded polarimetric sensors while the angular orientation of embedded FBGs written in HB fibers is responsible for the observed optical wavelengths shifts.
