Paper Abstract

In this paper we present the implementation of a multi-point fiber optic sensor for monitoring different concentrations of contaminants in water. The experimental set-up consists in two fiber structures built each one by splicing of Single Mode-Multimode-Single Mode (SMS) segments. Both structures are operating in a multimode interference regime and collocated in parallel geometry. The experimental results show the simultaneous detection in transmission configuration for water and salt (0% - 30% w/w) and water-glycerin (0% - 40% w/w) blends. The advantage of the proposed system has a simple construction, low cost, linear response and each sensing point works independently one of other.
