| 摘要 |
The present invention relates to an opto-mechanical transducer comprising an optical fibre exhibiting a polished pointed distal end placed opposite a reflecting surface and a proximal end being linked up to a coupler combining an illumination optical fibre associated with a light source and a measurement optical fibre associated with a photo-detector. The reflecting element exhibits a movable zone with an axial component, the axial distance between the distal end of the optical fibre and said reflecting surface at rest is determined so that the reflected luminous intensity I0 is equal to P.Imax where Imax denotes the maximum reflected luminous intensity, and P is a parameter lying between 0.25 and 0.75. |
