近年来,国内外光导纤维的应用除光通信领域外,同时又在传感器应用方面得到迅速发展。光导纤维能将光能从直经几微米的可挠性介质的一端输入,并以低损耗传输到几公里以外的另一端,即能构成一种在自由度和传输距离方面传统光学装置所无法比拟的传感器。而光导纤维具有体积小、重量轻、响应快、电绝缘和抗干扰性能好等特点,特别适宜于在易燃易爆及强磁场环境下长期工作。随着其可靠性和稳定性的不断提高,应用范围也越来越广。这里介绍七种类型的传感器:
In recent years, optical fiber applications at home and abroad in addition to the field of optical communications, but also in sensor applications has been rapid development. An optical fiber can input light energy from one end of a flexible medium just a few microns and transmit it to the other end a few kilometers away with a low loss, so that a conventional optical device can not be formed in a degree of freedom and transmission distance Compared to the sensor. The optical fiber with small size, light weight, fast response, electrical insulation and anti-jamming performance is good, especially suitable for long-term work in the flammable and strong magnetic field environment. With the continuous improvement of its reliability and stability, the application scope is also getting wider and wider. Here are seven types of sensors:
