The device (1) has a lighting unit (9) with a light screen (11) for generating a light reflection on a bottle (7). Cameras (3) detect the light reflection. Areas (21a, 21b) of different luminance are formed on the light screen. The areas are arranged in a stripe pattern that comprises two to four dark stripes. The areas are arranged alternately in the horizontal direction. The light screen comprises a foil (17) in and/or on which the areas of varying luminance are formed. The foil is arranged between a light source (13) i.e. LED background lamp, and a diffusion screen (15) of the light screen. An independent claim is also included for a method for detecting elevations and/or depressions on bottles in a labeling machine using an inspection device. |
