Hardware Design of Integrated Platform of Optical Fiber Sensor Based on Temperature Distribution

The distributed fiber sensing technology can calculate the temperature and strain distribution on the fiber by detecting the scattered light intensity along each position of the fiber. Brillouin optical time domain analyzer is a distributed optical fiber sensing technology, which is suitable for long distance, large range and high sensitivity distributed optical fiber sensing system, and can achieve accurate real-time measurement of temperature and strain on the optical fiber. It has important research significance and practical value. In this paper, brillouin scattering effect and BOTDA sensing principle in optical fiber are studied. Based on the signal characteristics of BOTDA sensing system, a distributed optical fiber sensing system test platform is designed.
