Abstract (en)
[origin: WO2004104566A1] The invention relates to a method and a device for optically controlling the quality of objects having a preferably circular edge. According to the invention, light is oriented towards the edge of the object and the light radiated from the object by reflection, refraction and/or diffraction is detected by means of a measuring device (1). Defects on and/or in the object are determined on the basis of the detected image signals.
