光纤传感器的发展综述

摘要

对光纤传感器的原理、特点及国内外的发展情况作了论述，介绍了在实际测量中的一些具体应用，提出了光纤传感器在轨道交通地铁隧道结构的垂直方向和水平方向的位移及隧道的收敛位移测量的运用前景等，为光纤传感器的深入研究提供了一定的指导。%The paper indicates the principles and features for optical fiber sensor and its development at home and abroad, introduces the factual application in some measurement, and points out the application perspective of optical fiber sensor in the displacement in the vertical and horizontal directions of the tunnel structures of the track traffic and the convergence displacement measurement of tunnels, and provides certain direction for the deep research on optical fiber sensor.
