Abstract
A simple fibre sensor for continuous monitoring of refractive index variations of liquid mixtures is described. The principle of this sensor, based on the excitation of a surface plasmon at a metal/dielectric interface, has been descibed in previous articles. In this paper it is shown that this set-up, which uses monochromatic incident light, can work as a refractive index variation sensor either in a range between 1.36 and 1.40 when using a single silver layer or in a range shifted down to 1.33 when coating silver by a thin TiO2 adaptative layer obtained by sol-gel process.
