ABSTRACT:
An apparatus designed to examine a surface includes a polarization analyser element, or analyser, placed in the path of a light beam reflected by the surface, a device configured to take digital images and placed in the path of the beam reflected by the surface downstream of the analyser, and a processing unit capable of calculating the color and the intensity of a plurality of pixels of at least one image.
