Summary:The station (1) has a lighting system (6) e.g. LED, to supply light beams illuminating an object inspection zone. A camera (8) is equipped with lens and captures images of the zone during rotation of a hollow object (2). An analysis and processing unit analyses and processes the images to detect the presence of defects reflecting in the images. Optical deviation elements (11) e.g. Fresnel lens, are placed between the zone and the lens for deviating rays reflected by the zone into the air to form a set of views of the zone, in each image, taken under different illumination angles.
