摘要	Fibre optic particle detector for measurements in a fluid flow, comprising an optical fibre being acoustically coupled to a mechanical element adapted to be acoustically coupled to the flow, a fibre optic interferometer and a light source providing light in said optical fibre.
其他摘要	用于在流体流中进行测量的光纤粒子检测器，包括声学耦合到适于声学耦合到流动的机械元件的光纤，光纤干涉仪和在所述光纤中提供光的光源。
主权项	Fibre optic particle detector for measurements in a fluid flow, comprising an optical fibre, an optical interferometer, an optical light source providing light in said fiber, the optical fiber being attached to or embedded in a transducer element, characterized in that the transducer element or a mechanical structure which is in acoustic contact with the transducer element is arranged to be hit by particles moving in the flow by exposing part of said transducer element or said mechanical element to the flowing fluid, each particle hitting the exposed part thus generating acoustic waves propagating some distance in the mechanical structure and/or transducer element to the optical fibre.
