Paper Abstract

A vibration sensing technique using the speckle contrast ratio from a multimode fiber is introduced. This sensing technique is based on time integration by a CCD camera, from which the contrast ratio of the speckle patterns can be measured. Important aspects of the proposed sensor are that it can be applied to high-frequency vibration sensing and that its operation is rather simple.
