DEVICE FOR MEASURING DEFORMATIONS ALONG AT LEAST ONE OPTICAL FIBRE, USE OF AN OPTICAL FIBRE TO MAKE A MEASUREMENT OF DEFORMATIONS AND METHOD OF MEASURING DEFORMATIONS |
摘要 |
<p>The invention relates to a device (100) for measuring deformation along at least one first optical fibre (10). Such a measuring device (100) comprises the first optical fibre (10) and an optical system (20) linked optically to the first optical fibre (10) and adapted for making a measurement according to the principle of Brillouin measurement so as to determine the deformation along the first optical fibre (10). The first optical fibre (10) comprises a fibre core with a molar proportion of alumina of at least 6%. The invention also relates to the use of such a first optical fibre to measure the deformations and a method of measuring deformation.</p> |
