Paper Abstract

In this work, an all-fiber loop mirror using a clover microstructured fiber for the simultaneous measurement of temperature and strain is presented. The sensing head is formed by a short piece of clover microstructured fiber with 35 mm length. The geometry of the fiber allowed observing different interferences created by the microstructured fiber core section. Different sensitivities to temperature and strain were obtained and, using a matrix method, it is possible to discriminate both physical parameters. Resolutions of ±2ºC and ±11 με, for temperature and strain, respectively, were attained.
