    摘要:

    光纤形态传感技术是解决柔性体形态测量、光电缆实时形态跟踪、医疗介入针轨迹实时跟踪等等3D形态恢复问题的创新型技术方案。光纤形态传感技术以光纤为传感主体,不需要视觉接触,易于安装、嵌入,耐腐蚀,抗电磁干扰,适用于水下、地下等复杂环境中的大尺度结构形态测量,在水下安防、灾害预警、医疗器械等领域具有广泛的应用需求。在过去二十年间,随着社会的发展,形态传感需求在各领域日益迫切,这一课题也受到了国内外学者的青睐。本文根据近年来光纤形态传感技术的研究进展,按照光纤形态传感技术的实现过程,将光纤形态传感技术分为光纤曲率传感器、全向型光纤曲率传感器和光纤形态传感器三个阶段,并分别介绍了各阶段传感器的实现方法以及难点问题。

    Abstract:

    Optical fiber shape sensing technology is an innovative technology solution to solve the 3D morphology recovery problems of flexible body morphometry, optical cable real-time morphology tracking, real-time tracking of medical interventional needle trajectory and so on. Optical fiber shape sensing technology takes optical fiber as the sensing body, does not require visual contact, is easy to install, embedded, corrosion resistant, anti-electromagnetic interference, suitable for underwater, underground and other complex environment in large-scale structure morphology measurement, has a wide range of application needs in underwater security, disaster warning, medical instruments and other fields. In the past two decades, with the development of society, the demand for shape sensing has become increasingly urgent in various fields, and this topic has been favored by scholars at home and abroad.In this paper, based on the research progress of optical fiber shape sensing technology in recent years, according to the realization process of optical fiber shape sensing technology , we divided the optical fiber shape sensing technology into optical fiber curvature sensor, omnidirectional optical curvature fiber sensor and optical fiber shape sensor, furthermore ,we introduced the method of sensor and the difficult points in different stages.
