Paper Abstract

We have been developing "fiber optic nerve systems" for "smart structures and smart materials," in which an optical fiber acts as sensor to measure distribution of strain and/or pressure along it. By embedding the fiber in structures and materials, such as buildings, bridges, aircraft fuel-tanks and pipe-lines, we can realize health monitoring function for these. We have created an original technology to analyze the distributed optical parameters along the fiber by use of synthesis of correlation characteristics of continuous lightwave. Adopting this technology, "fiber optic nerve systems," which have quite a high spatial resolution and measurement speed, have been established.
