Inspection system for visually inspecting objects, in particular the surface of objects, during their transport along a transport path, the system comprising a free space allowing the objects to pass through the system and including an inspection area in which the objects are inspected visually,an illumination device for illuminating at least the peripheral surface of an object in the inspection area, and a plurality of camera/sensor devices, each of them being configured to take an image of a surface section of said peripheral surface in its respective field of view by receiving light running along a respective light path from the illuminated object to the camera/sensor device, the fields of view of the camera/sensor devices in combination providing for full peripheral coverage of azimuth angle 360° of the inspection area wherein the length of at least one of the light paths is longer than the spatial distance between its ends. |
