Active fiber detectors
A fiber optic sensor is a small device in which optical fiber is used both as a data transmission line and as a sensing element capable of detecting changes in various quantities. The elements used in fiber optic sensors are completely passive with respect to electricity, which allows them to be used in various industries.
Fiber optic detectors are devices used in many industries to determine the concentration of substances, rotation speed, refractive index, stress, pressure, liquid level, temperature, vibration, acceleration, position in space. Optical fiber type of sensors is becoming more and more widespread for recording changes in parameters during technological processes due to their stability over a long period of time, resistance to interference of an electromagnetic nature, the possibility of contactless measurement and other advantages.
The basis for measuring the value by which the listed values change in the course of certain influences is the study of the indicators of the reflected beam of light transmitted through an optical fiber.
