Polarization-based fiber optic smart structures

摘要

Results of the studies on polarimetric fiber optic sensing based on polarization effects in fiber optic smart structures are presented. The smart structures consisted of highly birefringent (Hi-Bi) bow-tie and side-hole fibers embedded in a specially prepared cylindrical epoxy cylinder. The applied procedure had an objective to investigate and compare the influence of the external structure on optical properties of different types of Hi-Bi fibers. The Hi-Bi fiber-based structure has been subjected to selected deformation effects mostly induced by hydrostatic pressure (up to 300 MPa.) and temperature, whereas polarization properties of the transmitted optical signal have been investigated.
