Abstract
The invention relates to a method of classifying and flow measuring the refringence of at least two populations of particles present in a fluid. The method uses a light source that has small coherence time, with a coherence length Lc<100 μm, that is used under extinction conditions at a center wavelength selected as a function of a range of volumes and of a range of refractive indices expected for the particles under consideration. The method uses a device that, together with the light source, forms a converging illuminating beam of aperture angle that is selected as a function of the range of volumes and the range of refractive indices expected for the particles under consideration at the selected center wavelength.
