Dynamic polarization based fiber optic sensor

Abstract

An optical fiber sensor system includes an optical fiber. A linear polarizing component is configured to communicate with the optical fiber. The linear polarizing component includes a polarization sensing fiber to be disposed adjacent to and preferably collinear with the optical fiber. A light source communicates with the linear polarizing component for generating a light signal along the optical fiber. A reflector is disposed along the optical fiber for reflecting back the light signal along the optical fiber. An optical detector communicates with the linear polarizing component. A signal processor communicating with the optical detector and configured for determining from the reflected light signal dynamic events along the optical fiber.
