Abstract
A method for determining a rate of sedimentation or of creaming of a mixture in suspension, including an application of a sample of the mixture in suspension to a photonic microresonator, an application of a first optical signal at the input of the photonic microresonator carrying the sample of the mixture in suspension, an acquisition and a recording of a second optical signal, delivered at the output of the microresonator carrying the sample of the mixture in suspension, and a determination of information representing a rate of sedimentation or of creaming of the mixture from the recorded second signal, by successive iterations of spectral analysis of the second optical signal.
