Popis:	A phase sensitive fiber optic strain gauge that is both spatially local and unidirectional is described. The design consists of a path balanced lead-in/out Michelson interferometer using a single-mode directional coupler. It is tested as a surface adhered device in both uniaxial and rosette configurations. The device is integrated between plies of graphite/PEEK thermoplastic to provide lamina strain measurements. Performance parameters gauge factor, transverse sensitivity, and failure strainmare evaluated. The utility of such a strain gauge is discussed in the general context of smart structures and skins.
