The invention concerns a method for non-destructive control of the condition of a surface likely to be cracked, using a method based on the observation of the wave emitted by a dye product applied on the surface and in the cracks, under the effect of an incident excitation beam of wavelength suited to the dye product. The invention is characterised in that it consists in using the rotation of the rectilinear polarised wave emitted by the dye product according to the thickness of the dye relative to an incident rectilinear polarised light wave, for eliminating from observation the spots caused by the residual dye product present on the surface. On the drawings, figure (1) is a laser, figure (2) is an observation camera and figure (3) a polarised wave analyser. The invention is applicable to dye penetration inspection and magnetic particle inspection.

Image Procédé de contrôle non destructif de l'état d'une surface susceptible de présenter des fissures, par une méthode basée sur l'observation de l'onde émise par un produit colorant appliqué sur la surface et dans les fissures, sur l'effet d'un faisceau d'excitation incident de longueur d'onde appropriée au produit colorant, caractérisé en ce qu'on utilise la rotation de l'onde polarisée rectiligne émise par le colorant en fonction de l'épaisseur du colorant par rapport à une onde de lumière polarisée rectiligne incidente, pour éliminer de l'observation les tâches dues au produit colorant résiduel présent sur la surface. Sur les figures, (1) est un laser, (2) est une caméra d'observation et (3) un analyseur d'onde polarisée. Application aux techniques de ressuage et de magnétoscopie.
