OPTICAL SENSOR FOR DETECTION OF AT LEAST ONE CHEMICAL SUBSTANCE AND OPTICAL PROBES COMPRISING SUCH OPTICAL SENSORS

摘要

P Optical sensor for the detection of at least one chemical substance, comprising an optical fiber (1) comprising, on the one hand, a heart waveguide (2) inside which propagates a light of excitation produced by a light source, and on the other hand, a sheath (3) surrounding the core waveguide (2). The optical fiber (1) comprises a sensitive zone (7) on which a material is arranged attractor (6) chosen to selectively attract at least one chemical substance to be detected, and in that the sensitive zone (7) of the optical fiber is adapted to allow the excitation light to interact with the chemical substance to produce a radiation to be detected. / P
