Title: VIBRATION SENSOR, VIBRATION MEASURING ARRAY, CHEMICAL SENSOR AND DEVICE COMPRISING SAME
Abstract:
The invention relates to a vibration sensor, particularly a microphone or hydrophone, having a first resonance element and a first optical interferometer which comprises a first measuring path and a first reference path, wherein the first measuring path is formed by a first measuring optical fibre and the reference path is formed by a first reference optical fibre, characterised in that the resonance element comprises the measuring optical fibre such that a first mechanical vibration of the first resonance element leads to the first measuring optical fibre substantially following the first mechanical vibration, wherein the first mechanical vibration can be applied to the first resonance element substantially from a first vibration direction, and the reference optical fibre is mechanically decoupled from the measuring optical fibre. A vibration sensor of a completely new kind can be provided in this way.
