Image-acquiring equipment equipped with telecentric optical objective with primary cylindrical lens

Image-acquiring equipment adapted to acquire an image of an object (15, 37) lacking perspective parallax, said equipment comprising:

• a lighting apparatus (34);
• a handling system (38) of the object (15, 37);
• characterized in that it further comprises:
• a linear camera (24) equipped with a linear image sensor (26);
• a telecentric optical objective (27) composed of:
• an optical assembly (13) for forming a real image (16) of the object (15, 37) placed between the linear camera (24) and the object (15, 37);
• a diaphragm (20) placed between the optical assembly (13) and the object (15, 37), said diaphragm (20) having an opening (21);
• and
• a main lens composed of a cylindrical lens (23), placed between the diaphragm (20) and the object (15, 37) so that:
• an optical axis (AO) of the cylindrical lens (23), passing through the opening (21) of the diaphragm (20) and the optical assembly (13), orthogonally intersects a plane of the image sensor (26) in its central point;
• a cylindrical axis (AC) of the cylindrical lens (23) is orthogonal to the optical axis (AO) which is also the main axis of the image sensor (26).
