コヒーレンス関数の合成による高空間分解能分布型光ファイバセンサ

“Fiber optic nerve system” has became a major research subject in the field of Optical Fiber Sensors. Optical fibers act 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 to develop “smart structures and smart materials.” In this paper, recent progress in “Fiber optic nerve system” is presented. Quite a high spatial resolution and measurement speed, compared with conventional ones, have recently been realized by applying a technique to synthesize shapes of optical coherence function.
