The application of fiber optic sensors is very broad, mainly in the following areas:

    Application of interferometric gyroscope and potentiometer rotary position sensors in bridge, dam and oilfield in urban construction. Fiber optic sensors can be embedded in concrete, carbon fiber reinforced plastics and various composite materials for testing stress relaxation, construction stress and dynamic load stress, in order to assess the short-term bridge construction phase and long-term operation of the structural performance.

    In the power system, it is necessary to measure the temperature, current and other parameters, such as the high-voltage transformers and large motor stator and rotor temperature detection, due to electrical sensors susceptible to electromagnetic interference, can not be used in such occasions, Fiber Optic Sensor. For example, distributed optical fiber temperature sensor is a high-tech developed in recent years for real-time measurement of temperature field distribution in space.

    For the production of flammable and explosive materials and equipment temperature measurement. Fiber-optic sensors in essence is a fire explosion-proof devices, it does not require the use of flameproof measures, very safe and reliable. Compared with the electrical sensors, both reduce costs and improve sensitivity.

    In addition, it can also be used in railway monitoring, rocket propulsion system and oil well testing and so on.

    In short, the Internet of things and fiber-optic sensing are complementary and mutually reinforcing role. Fiber has the advantages of broadband, high capacity, long distance transmission and multi-parameter, distributed and low energy sensing. Optical fiber sensing can continue to learn new technologies of optical fiber communication (such as new semiconductor light source, new fiber), new devices, various fiber optic Throttle Motor Position Sensor are expected to be widely used in the Internet of things. Optical fiber technology in the Internet of Things has a very broad application prospects, all-optical Internet of things in the future is expected to bring a new form of things.
