Abstract (en)
[origin: DE102013105693A1] The method involves generating an illumination surface (4) consisting of parallel light beams by a light source (1). The object (8) is partially illuminated by the illumination surface. A change of the parallel light beams of the illumination surface is detected by the object. The light beams coming from the illumination surface are projected on a projection surface (5) that is arranged behind the object. The shadow impact generated by the illumination surface on the projection surface is detected with an optical detection unit (7). An independent claim is included for a device for optical inspection of an object.
