光纤传感器是随着光纤通信发展而出现的新一代传感元件。它与传统的传感元件相比,具有不受电磁干扰、没有噪声、灵敏度高、反应速度快、体积小、重量轻以及可以实现远距离的非接触传感等许多特点。光纤传感器大致可以分为两类,一类是把光纤作为传输线路来使用,另一类是把光纤既作传输线路使用,同时又作传感元件使用,前者称为传输型光纤传感器,后者称为功能型光纤传感器。国外对光纤传感器的研究是从1977年开始活跃起来的,至今已公开报导的光纤传感器超过了100种,并已在工业、军事、医疗
Fiber optic sensor is a new generation of sensing element that appears with the development of optical fiber communication. Compared with the traditional sensing element, it has many characteristics such as no electromagnetic interference, no noise, high sensitivity, fast response, small size, light weight and long-distance non-contact sensing. Optical fiber sensors can be divided into two categories, one is the use of optical fiber as a transmission line, and the other is the use of optical fiber both for transmission lines, but also for sensing components, the former known as transmission type optical fiber sensor, the latter Known as functional optical fiber sensor. Foreign research on optical fiber sensors has been active since 1977, so far there are more than 100 kinds of optical fiber sensors that have been publicly reported, and have been widely used in industry, military, medical
