Title (EN) DISTRIBUTED OPTICAL CHEMICAL SENSOR
(FR) CAPTEUR CHIMIQUE À FIBRE OPTIQUE DISTRIBUÉ
Abstract:
(EN) The invention relates to a sensor system comprising a waveguide, which waveguide comprises a grating in at least a part of the waveguide, which waveguide further comprises a coating, the coating comprising a polymer, which polymer comprises a chain, in which chain are present an aromatic group and a chemical group selected from the group of sulfonyl groups, carbonyl groups, carbonate groups, fluorocarbon groups, siloxane groups, pyridine groups and amide groups.
(FR) La présente invention concerne un système de capteur comportant un guide d'ondes, ledit guide d'ondes comprenant un réseau dans au moins une partie du guide d'ondes. Ledit guide d'ondes comporte également un revêtement, le revêtement comprenant un polymère, et ce polymère comporte une chaîne dans laquelle sont présents un groupe aromatique et un groupe chimique choisis parmi les groupes sulfonyles, les groupes carbonyles, les groupes carbonates, les groupes fluorocarbones, les groupes siloxanes, les groupes pyridines et les groupes amides.
