Abstract
The apparatus comprises a light projector emitting light rays along a central longitudinal axis and a light shaping device for creating a central symmetric geometric figure of light in a plane running perpendicular to the above mentioned central longitudinal axis. A mirror assembly having a central aperture deflects the central symmetric geometric figure of light towards the center of the aperture. In this way, a thin sheet of light is created extending perpendicular to that central axis and evenly illuminating the object. A support member holds the object in the center of the aperture and is movable along the central longitudinal axis for passing the object through the thin sheet of light. A photographic camera having an optical axis coinciding with the afore mentioned central longitudinal axis of the light projector is located behind the mirror assembly to capture the portions of the object illuminated by the thin sheet of light.
