Abstract
This method for characterizing a state of adhesion of the particles is applied via a system including a source of spatially coherent light and a photodetector array, the particles being contained in a liquid medium, the liquid medium being delimited by a transparent surface, the particles being able to adhere to the transparent surface. The method includes: illuminating the medium with the source of spatially coherent light; acquiring at least one image by the photodetector array, the image being formed by radiation transmitted by the illuminated medium and including at least one elementary diffraction pattern, each elementary diffraction pattern corresponding to waves diffracted by a particle during the illumination of the medium; and computing, from at least one acquired image and for at least one particle, a primary indicator characterizing the state of adhesion of the particle to the transparent surface.
