Distributed Fiber Optic Sensor DTS
Distributed temperature sensing systems (DTS) are devices which measure temperatures by means of functioning as linear. Temperatures are recorded along the optical sensor cable, thus not at points, but as a continuous profile. A high accuracy of temperature determination is achieved over great distances. Typically the DTS systems can locate the temperature to a spatial resolution of 1 m with accuracy to within ±1 °C at a resolution of 0.01 °C. Measurement distan.

What is the sensing principle of fiber optic sensors
A fiber optic sensor measures a physical quantity by modulating the intensity, spectrum, phase, or polarization of light traveling through the optical fiber system. It's a device that converts light rays into electronic signals. This signal can then be measured by an instrument or interpreted by a user. Radiation absorption creates electronic excited states that are trapped by localized defects for extended periods of time. Heating the material enables the trapped states to interact with phonons and decay into lower-energy. Optical fibers provide sensing solutions for many types of applications and environments with high performance.
