We also show how this technique can be used to perform distributed photothermal measurements of gas presence in suitable microstructured fibers. %K Distributed fiber-optic sensor %K Phase-sensitive reflectometry %K Distributed acoustic sensor %K Temperature sensor %K Strain sensor %K Electrónica %K Electronics %~ Biblioteca Universidad de Alcala
