Abstract

The study of bidirectional interrogation techniques required in the development of white light interferometric sensor arrays was presented. The technique involved the designing of a multiplexed fiber optic deformation sensor loop network suitable for smart structure applications. The multiplexed direction interrogate sensing system suffered from large fiber segment-induced optical reflectance and insertion losses. The sensor loop technology obtained absolute length measurement for each sensing fiber segment and thus proved to be an efficient quasidistribution strain or temperature measurement technique.
