Abstract

The invention concerns a method for evaluating a fluid including evaluating the refractive index corresponding to the spectral analysis of the reflection by the mixture of a light beam, conveyed from a light source to within the mixture by a waveguide, said light source being capable of emitting in two separate wavelengths.
