Optical fiber hydrogen sensor for detecting renewable fuels in aeronautic field, has cavity formed inside sensorial head of optical fiber laser, and laser pumped and emitted in cavity to measure hydrogen concentration

The sensor has a cavity formed inside a sensorial head of an optical fiber laser. A hydrogen concentration is measured by pumping and emission of the laser in the cavity. Fibre optic laser hydrogen sensor. Fibre optic hydrogen sensor, consisting of a fibre optic laser and a sensor head incorporated inside the laser cavity, which is characterised by the fact that the measurement of the hydrogen concentration is obtained from the time which transpires from when the laser pumping starts until the first laser peak is emitted. For use in the field of new renewable fuels for automobiles and spacecraft, in relation to the detection of leakage of fuel.The sensor has a cavity formed inside a sensorial head of an optical fiber laser.
