SENSOR BASED ON MICRO-STRUCTURED OPTICAL FIBER AND A BRAGG NETWORK

摘要

A Bragg grating fiber sensor comprising a source and a detection system operating at a given study wavelength, as well as a Bragg grating fiber (1) connected to said source and said system said fiber being a microstructured optical fiber whose sheath (5) comprises channels (3) adjacent to the core (2) and able to receive an analyte, the diameter of the core (2) being of the order of length study wave.
