    Abstract: A system and method for remote object sensing which features a spatially polarization-inhomogeneous light beam that is directed on the remote object. A polarimetry receiver receives the light beam after it contacts the remote object. The changes in the spatially polarization-inhomogeneous light beam from contacting the remote object are a result of spatial features of the remote object. The polarimetry receiver is configured to measure the spatially inhomogeneous electric field of the light beam after it contacts the remote object and compute the changes in the spatially polarization-inhomogeneous light beam in order to detect spatial features of the remote object. The system obtains high-resolution, real-time information concerning important spatial features of the remote object.

    Abstract: Methods and systems of sensing conditions in a fiber includes launching a light beam into a fiber. A first branch of scattered light is set to a mode other than a fundamental mode. A second branch of scattered light is optically filtered to remove unscattered input light. Brillouin scattered light is coherently detected on the first branch to produce a combined temperature/strain profile of the fiber. Raman scattered light on the second branch is directly detected to produce a temperature profile of the fiber. A strain profile of the fiber is determined, using a processor, based on the combined temperature/strain profile and the temperature profile.
