ABSTRACT:
Active chemical sensor with optical fiber and its production process.
The chemical sensor according to the invention makes it possible to measure a given quantity or magnitude of a fluid. It has a chemical reagent suitable for the measurement and for reacting with the fluid, a support means (20a, 28) for the reagent and a single optical fiber (20) for supplying light to the reagent and recovering the light reflected by the reagent, said sensor being characterized in that the support means incorporates a vinyl imidazole polymer or copolymer film (28) in which the reagent is immobilized, said polymer being in particular directly grafted on to one of the ends (20a) of the optical fiber (20).
