光纤传感器是光纤应用领域的最新成就,近年来无论在质量还是数量上都有了较大的进展,其精度、感度、稳定性等方面有了很大提高。特别是光纤传感器材料得到更多的开发,是目前光纤传感器领域最有吸引力的课题。光纤传感器可分为传感到(或叫功能型)和传光型两大类。传感型是指用光纤本身作为敏感元件的传感器;传光型是指利用其它敏感元件测得物理量后,以光纤作为数据传输线路的传感器。表1收集了现已设想的用于光纤传感器的各种材料。
Optical fiber sensor is the latest achievements in the field of optical fiber applications, in recent years both in quality and quantity have made great progress, its accuracy, sensitivity, stability and so has greatly improved. In particular, more development of optical fiber sensor materials is the most attractive issue in the field of optical fiber sensors. Optical fiber sensor can be divided into sensing (or called functional) and the two types of light transmission. Sensing refers to the use of optical fiber itself as a sensor sensor; light transmission refers to the use of other sensors to measure the physical quantity, the optical fiber as the data transmission line sensor. Table 1 collects the various materials now contemplated for fiber optic sensors.
