    摘要： The present invention is related to a method for determining distributed temperature variation of a few mode optical fibre comprising the steps of:—providing a few mode optical fibre;—enlighting a first end of said few mode optical fibre by means of a coherent light source;—determining the interference pattern of coherent light at a second end of the optical fibre;—selecting one maximum of intensity at the second end of the optical fibre by spatially filtering the enlighting at the first end of the optical fibre;—determining the path length of the trajectory of the selected maximum of intensity;—based upon the determined path length of the trajectory of the selected maximum of intensity, determining the temperature variation of the few mode optical fibre.

    摘要： Multi-use gas sensors according to the invention are adapted for use in an oxidising atmosphere; they comprise an optical fibre having a temperature sensitive detection zone and an associated reaction layer associated with an external surface of the optical fibre at at least one position along the fibre's length; the reaction layer is adapted to generate a temperature change when brought in to contact with a gas to be sensed.
