Fiber optic nerve systems with optical correlation domain technique for smart structures and smart materials

Abstract

We have developed 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. In our laboratory, an original technology to analyse the distributed optical parameters along the fiber by use of synthesis of correlation characteristics of continuous lightwave has been developed. Adopting this technology, fiber optic nerve systems with a high spatial resolution and a fast measurement speed have been established. © 2005 Springer.
