Introduction to Fiber Optic Vibration Sensors
By burying a fiber optic cable underground, it is possible to monitor vibration and sound information from several tens of kilometers away and transmit it to the central computer room. By analyzing the sound wave information, the type of event can be determined. Through terminal devices, optical fibers have become industrial information sensors from data transmission media. Fiber optic sensing technology, as an important branch of sensor technology, belongs to the sensing and input part of the Internet of Things. In the future Internet of Things, fiber optic sensing technology and its composed sensing network will play an important role in the sensing end of the Internet of Things. The Internet of Things has been applied in fields such as security, electricity, μεταφορά, logistics, healthcare, and environmental protection, and its application models are becoming increasingly mature. Sensors and related intelligent instruments are at the level of information perception in the Internet of Things, accounting for a certain proportion of the entire Internet of Things industry. Fiber optic sensing technology, as an important branch of the sensor and intelligent instrument industry, has very broad application prospects.
Fiber optic vibration sensing is the process of applying vibration to optical fibers, resulting in changes in optical properties such as intensity, wavelength, frequency, phase, skewness, κλπ., which are also conducted simultaneously. By measuring these changes, the vibration signal is reconstructed. Fiber optic vibration sensors have advantages such as good resistance to electromagnetic interference, large monitoring range, υψηλή ευαισθησία, and relatively simple systems. Επομένως, they have successfully replaced traditional vibration sensors in many fields.
There are many types of fiber optic sensors, including temperature, πίεση, flow rate, displacement, vibration, rotation, bending, and so on. Vibration is just one type of fiber optic sensing, and each type of fiber optic sensing implies completely different application scenarios.
Traditional sensors are point based and cannot be distributed. Fiber optic sensing, as a distributed sensor, can accurately measure stress, θερμοκρασία, vibration and other information at any point along the fiber optic line. Based on temperature, vibration, and stress, it is possible to extend the monitoring of many projects.
With the rapid development of China, many industries such as manufacturing and industry have a strong demand for sensors, and the sensor market is very large.
Fiber optic sensing has unique advantages such as wide range, long distance, and distribution. So the technological advancement of sensors in the future will also drive the progress of the entire society.
