We have studied “fiber optic nerve systems” for “smart structures and smart materials,” in which an optical fiber acts as a sensor to measure distribution of strain or pressure along it. In our laboratory, an original technique has been developed to analyze the distributed optical parameters along the fiber by use of synthesis of correlation characteristics of continuous lightwave. By this technique, “fiber optic nerve systems” with a high spatial resolution and a fast measurement speed have been developed.
