Abstract
A detection system includes a length of optical fiber and an OTDR coupled to the optical fiber. The OTDR includes a radiation source providing pulsed radiation to the fiber, a detector detecting radiation that is backscattered through the fiber, and a processor capable of analyzing the variation of the radiation that is backscattered through the fiber. At least two polarization dependent sensing elements are positioned along the length of optical fiber.
