Abstract (en)

[origin: WO2010075846A1] The invention relates to a device for optically inspecting an at least partially reflecting surface of an item, having a first and at least one second crossbeam (12, 14) each forming a section (32) largely in the shape of a circular segment. The crossbeams (12, 14) are disposed at a longitudinal distance (D) from one another, defining a longitudinal axis (17). The two crossbeams (12, 14) are held at the longitudinal distance (D) by means of a plurality of longitudinal beams (16). The longitudinal beams (16) are disposed at a defined radial distance (38) from the sections (32) in the shape of circular segments. The crossbeams (12, 14) support a light-transparent diffusing screen (34) forming a tunnel-shaped inspection space (36). A plurality of light sources (48) are disposed outside of the tunnel-shaped inspection space (36) behind the diffusing screen, said sources being controllable individually or in small groups in order to generate variable light-dark patterns (90) on the diffusing screen. At least one camera (74, 78) is set up in the tunnel-shaped inspection space (36).
