Abstract
NOVELTY - The system has an objective (16) assigned to a light source, to produce a light beam (B), at least one grid (19) arranged in the beam path on the objective. A first imaging system (22) images the grid on a measuring plane (F3) intersecting or at least partly coinciding with the body surface. A second imaging system (32) receives reflected or scattered light. A CCD camera (36) is used to take the image produced by the second imaging system. USE - Optical determination of shape of surface of a body. Reproduction of 3D shape of surface of body. ADVANTAGE - Larger bodies can be specified regarding their surface structure, depending on their shape. Fine or coarse structural surface measurement is significantly improved. DESCRIPTION OF DRAWING(S) - The figure shows the optical system. Objective 16 Grid 19 First imaging system 22 Surface of object 26 Second imaging system 32 CCD camera 36 Light beam B Measuring plane F3
