Abstract
A system including an optical waveguide having a length extending from an optical interrogator at a first end, a plurality of light-modulating sensor nodes disposed at predetermined locations along the length of the optical waveguide, and (in some embodiments) a plurality of first beam splitters at each of the predetermined locations along the length of the optical waveguide, each of the first beam splitters configured to direct a portion of an optical signal from the optical interrogator to one of the plurality of light-modulating sensor nodes along an optical waveguide path, and return a reflected optical signal to the optical interrogator in an opposite direction along the same optical waveguide path.
