FIBER OPTIC MEASURING DEVICE AND METHOD

摘要

The invention relates to a measuring device including at least one optical fiber (51, 52, 60) which contains a series of Bragg gratings (100, 101, 102, 103) distributed between a first end and a second end. A light source (10) arranged to emit a luminous flux at a plurality of wavelengths in the first end of the fiber (51), and an instrument (16) connected to the second end of the fiber for measuring the power of the light transmitted at each emitted wavelength, enable the implementation of the method consisting of measuring a power of the light transmitted by the optical fiber in a spectrum including said wavelengths.
