The engeneerized prototipe of a fiber-optic sensor useful for vibration measurement in hostile environments is presented.The vibrometer is essentially based on a "differential" heterodyne Michelson-type interferometer in which the reference beam and the sensing beam are both guided, with orthogonal polarization, by the same single-mode polarization-holding fiber. Measurements of large vibration amplitudes of rough metal surface are reported.
