Paper Abstract

This paper presents a novel, simple, low-cost and repeatable quasi-distributed optical sensor system using specially designed fibre Bragg gratings (FBGs). The main idea consists in modulation of optical power by inscribed FBGs. The optical power changes with regard to outer parameters which have an influence on dedicated FBGs. The unique configuration is provided by proper characteristics of FBGs spectra. Instead of advanced and high-cost systems we demonstrate a concept of a low-cost sensor network using specially correlated FBGs.
