DISPOSITIF D'EVALUATION DE L'ETAT DE MOUILLAGE D'UNE SURFACE, PROCEDE D'EVALUATION ET DISPOSITIF D'INDICATION ASSOCIE

A device (2) for evaluating the state of wetting of a surface (8) includes an emitter (4) emitting a beam (F, F1, F2) which is incident in the direction of the surface (8) and a single element (12) for receiving the beam reflected by the surface (8). The device includes: A polarization (10, 13, 14)...

description A device (2) for evaluating the state of wetting of a surface (8) includes an emitter (4) emitting a beam (F, F1, F2) which is incident in the direction of the surface (8) and a single element (12) for receiving the beam reflected by the surface (8). The device includes: A polarization (10, 13, 14) including a first polarization zone (13) and a second polarization zone (14) designed to polarize a first part (F1) and a second part (F2) of the beam in a first and a second polarization direction; and a evaluation element (28) for calculating a polarization ratio between the polarizations of the first part of the reflected beam and the second part of the reflected beam to evaluate the state of wetting of the surface (8). Also described is an evaluation process and an associated indicator device.
