1. A fault detection system comprising:
an outer housing; and
a detection component positioned within the outer housing, the detection component comprising:
a plurality of emitters and a plurality of detectors positioned around an examination area through which a wire is traversed, wherein each adjacent pair of emitters included in the plurality of emitters is spaced no more than 30 degrees apart and each of the plurality of detectors is positioned across the examination area from a corresponding emitter included in the plurality of emitters,
wherein each of the plurality of emitters is configured to emit a signal that is measured by a corresponding detector and the detection component is configured to detect one or more defects on a surface of the wire based upon changes in the signals measured by one or more of the plurality of detectors.
