Insulated from dirt, magnetic, acoustic, pressure, temperature, acceleration, gyroscope, displacement, liquid level, torque, photoacoustics, current, optical fiber sensors can be used for displacement, vibration, rotation, pressure, bending, strain, velocity, acceleration, current, magnetic field, voltage, humidity, temperature, sound field, flow, concentration, PH value and strain and other physical quantities. Optical fiber sensors have a wide range of applications, involving almost all important areas of the national economy and national defense and people's daily life, especially can be used safely and effectively in harsh environments, solving the technical problems that have existed in many industries for many years, and has a large market demand. It is mainly manifested in the following applications:
The application of interferometric gyroscopes and grating pressure sensors for bridges, dams, oil fields, etc. in urban construction. Fiber optic sensors can be embedded in concrete, carbon fiber reinforced plastics, and a variety of composite materials to test stress relaxation, construction stress, and dynamic load stresses to evaluate the structural performance of bridges during the short-term construction phase and in the long-term operating state.
In the power system, it is necessary to measure temperature, current and other parameters, such as the temperature detection in the stator and rotor of high-voltage transformers and large motors. Distributed optical fiber temperature sensor is a kind of high-tech used for real-time measurement of spatial temperature field distribution developed in recent years, distributed optical fiber temperature sensing system not only has the advantages of universal optical fiber sensor, but also has the ability to distribute and sense the temperature of each point along the optical fiber, using this characteristic we can continuously measure the temperature of each point within a few kilometers along the optical fiber, the positioning accuracy can reach the order of meters, and the measurement accuracy can reach the level of 1 degree, which is very suitable for the application of large-scale intersection temperature measurement.
In addition, fiber optic sensors can be used for railway monitoring, rocket propulsion systems, and oil well detection.
Optical fiber has the significant advantages of broadband, large capacity, long-distance transmission, and multi-parameter, distributed, and low-energy sensing. Optical fiber sensing can continue to absorb new technologies and new devices for optical fiber communication, and various optical fiber sensors are expected to be widely used in the Internet of Things.
