Abstract
The paper deals with a new multifiber temperature sensor, based on the rela tionship between temperature and the refractive index of a suitable referen ce liquid, which replaces a part of the fiber cladding. The sensing element , the microcontroller-based hardware, and the artificial neural network (AN N)-based measurement software are described. The results of the tests carri ed out in the range 40 degrees C-110 degrees C showed good prototype accura cy and repeatability (both contained within +/-0.5 degrees C).
