• 1. Introduction Optical fiber sensing takes advantage of the physical properties of light as it passes through the optical fiber to detect changes in temperature, strain and other parameters. Optical fiber has wide working frequency band and large dynamic range, which is suitable for remote measurement and remote control. It is an excellent low loss transmission line. Under certain conditions, optical fiber is particularly easy to accept the measured or field loading, and is an excellent sensing element. The optical fiber is electrically neutral, small in size, light in weight, flexible, anti electromagnetic interference, and good in radiation resistance. It is especially suitable for use in flammable, explosive, space restricted, strong electromagnetic interference and othe...
