The core technology of the distributed optical fiber temperature sensing monitoring system is the optical fiber laser radar technology, that is, laser light source is injected into the optical fiber.
In a pulse, most of the energy of the incident light travels to the end of the optical fiber and disappears, but the small part of the backward scattering light travels back along the fiber.
To. The backscattered light (Raman scattering light) is very sensitive to the temperature, and the whole root can be obtained by processing the real time signal analysis.
The temperature distribution curve of the optical fiber, so as to achieve the purpose of real-time temperature monitoring. The system can carry on the whole line, continuous, distribution of the monitoring object
Type measurement, positioning, monitoring and alarm.
