| Abstract: | The mathematical model based on Jones matrix is presented to study the polarization effect of the distributed optical fiber sensor. A solution is brought forward that the fiber sensor with a polarization controller can remove not only the linear birefringence, but also the orientation birefringence. The system is well against the polarization fading and the input light can be linearly polarized to a discretional angle. |
