Abstract
A method is provided for determining temperature changes of an optical fibre having Fiber Bragg Grating patterns provided in at least one portion of the optical fibre. The method involves: emitting light into the optical fibre in a first direction from a first detector arrangement, receiving reflections from the patterns of such emitted light by the first detector arrangement, and processing the reflections for determining a current temperature change related to the optical fibre; and on the basis of predetermined criteria, emitting light into the optical fibre in an opposite, second, direction from a second detector arrangement, receiving reflections from the patterns of such emitted light by the second detector arrangement, and processing the reflections for determining a current temperature change related to the optical fibre. A computer program product comprising program code for implementing the above-described method is also provided, along with an associated system and platform.
