Paper Abstract

The physical phenomenon behind the sensor described in this paper is related to the modulation of the speckle pattern, at the output end of a multimode fiber illuminated by coherent light, when the fiber is mechanically or acoustically disturbed. This effect is observed either when highly multimode fibers or two-mode fibers are used. In the latter case a demodulation technique is proposed to restore a signal proportional to the acoustical excitation
