1. A method for monitoring the compliance of a container, said container having a substantially cylindrical shape, said method comprising:
rotating said container about its longitudinal axis;
illuminating said rotating container with a first light source having a first wavelength;
acquiring, by means of a first acquisition device, a first image representative of any incohesive particles present on an inner and/or outer surface of said container;
illuminating said rotating container with a second light source having a second wavelength;
acquiring, by means of a second acquisition device, a second image representative of any defects on the surface of said container;
comparing said first image and said second image with reference parameters of said container;
notifying any defects of said container as a function of said comparison,
wherein said first light source has a different wavelength than said second light source;
wherein a dichroic mirror, mounted on a mirror support, is arranged so that said second light source is positioned behind said mirror support and emits a second light through said dichroic mirror for illuminating said rotating container, and
wherein said first light source is positioned so to emit a first light incident on a surface of said dichroic mirror for illuminating said rotating container and is emitted perpendicularly to said second light.
