摘要
A method of observing and analyzing optical singularities includes illuminating an outside of a container by using a light-emitting surface of axial symmetry around a vertical axis (Z) parallel to the axes of symmetry of the containers, with a property of the emission that is detectable by the acquisition system(s) varying along a generator line of the light-emitting surface. For containers of low transmittance, taking the view image of the container portion by the image acquisition device receiving light beams comes from a portion of the light-emitting surface situated on the same side of the container. For containers of high transmittance, taking the view of the container portion by the image acquisition device receiving light beams comes from a portion of the light-emitting surface that is diametrically opposite relative to the container.
