Abstract: The article presents a fiber-optic sensor based on a singlemode-multimode-singlemode (SMS) structure for simultaneous measurement of strain and curvature. It is shown that the simultaneous demodulation of strain and curvature can be realized using the Fourier analysis of the recorded interference oscillations

Keywords: optical fiber sensors, intermode interference, single mode – multimode – single mode, stretching, bending.
