The series of transformations that allow one to infer dataindicative of structural performance from the scalar optical data provided byembedded sensors is discussed. Specific topics that are emphasized includeforward and inverse phase-strain-temperature relations, the difference betweenfiber and structure measurands, and the uniqueness and stability of inferredstructural data.
