Comparative study of all optical fibers in different smart structures and non-destructive evaluation

This paper deals with comparative study of various types of optical fibers in non-destructive evaluation of different smart structures. Performance of single mode, high-birefringent, low-birefringent fibers, multifibers and plastic fibers embedded into concrete and composite structures are experimentally evaluated under different conditions. The results are discussed with respect to overall sensor performance and structural environment, which facilitates the selection of appropriate fiber sensor for a particular structure.
