A fiber-optic sensor for the measurement of strain is described, in which the measurand-induced changes in both phase and polarization state are simultaneously recovered. A simple optical arrangement based on the fiber Fabry–erot interferometer is used to realize a high-resolution instrument with enhanced measurement range.
