摘要：
The invention concerns a method for identifying in objects made of transparent material, for example, drink bottles, diffuse dispersion defects, wherein the objects concerned (10) are examined by means of a light source (12) and a camera (16), a contrast model (14) being arranged between the light source (12) and the object to be examined. The diffuse dispersion defects are identified on the basis of a decrease in the contrast effect of the contrast model (14) represented through the object.
