Distributed and Multiplexed Fiber Optic Sensors andtheir Applications to Smart Structures and Smart Materials

摘要

We have studied "fiber optic nerve systems" for "smart structures and smart materials," inwhich an optical fiber acts as a sensor to measure distribution of strain or pressure along it. In ourlaboratory, an original technique has been developed to analyze the distributed optical parameters alongthe 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 beendeveloped.
