Research on Polarization Control of Optical Fiber Sensing Technology for Leak Detection

摘要：

Optical fiber sensing pipe leak detection system is unstable because Polarization changes. The principle of polarization control has been analyzed; the expression of polarization control has been derived. Using simulated annealing algorithm programmed by VC++ and Labview, the dynamic polarization control of Optical fiber sensing pipe leak detection system has been realized. Simulation test and leak detection test shows that the algorithm is stable; the range of light intensity fluctuation is less than 1％.
