A POTDR System Based on Dual Sensing Directions
In this paper, a new distributed fiber optic sensor system based on dual sensing directions by polarization optical time-domain reflectometer (POTDR) is proposed. Using a single POTDR scheme, the system is able to detect signals in the forward direction and backward direction simultaneously. It can...

| description | In this paper, a new distributed fiber optic sensor system based on dual sensing directions by polarization optical time-domain reflectometer (POTDR) is proposed. Using a single POTDR scheme, the system is able to detect signals in the forward direction and backward direction simultaneously. It can detect more perturbations applied on the fiber simultaneously than a traditional POTDR. It can also improve the positioning accuracy of POTDR by judging the perturbations from both directions. The proposed method is cost effective and has good potential in the application of intrusion monitoring. |
