| 摘要 |
<p>The invention relates to a method for observing and analysing optical singularities, consisting: in illuminating the exterior of the container using a luminous surface (6) that is axially symmetric about a vertical axis (Z) parallel to the axis of symmetry of the containers, a variation of a property of the emission being detectable by one or more acquiring systems (11) along a generatrix of the luminous surface; in the case of low transmission containers, in imaging the container portion with the image acquiring device receiving light beams originating from that portion of the luminous surface (6) which is located on the same side of the container; or, in the case of high transmission containers, in imaging the container portion with the image acquiring device receiving light beams originating from that portion of the luminous surface (6) which is radially opposite relative to the container.</p> |
