Abstract :
This paper deals with a new fiber optic temperature sensor. The relationship between temperature and refractive index of a “reference” liquid is used to obtain a sensing fiber output that follows temperature changes of an external fluid with very low response time. The fiber optic sensing element and the low-cost measurement hardware are described in the paper together with the first experimental results
