ABSTRACT:
The invention relates to fiber optic methods and devices for sensing physical parameters, like temperature or force, by converting a fraction of the intensity of the interrogating light into a positive signal with wavelengths and/or light propagation modes different from those of the interrogating light. Preferred embodiments make use of the redistribution of the intensity of the interrogating light between the core and a secong light-guiding region of an optical fiber probe, and the processing of the light carried by said second light-guiding region into a positive signal separable from the interrogating light.
