A method is proposed for optical shape recording and/or evaluation of optically smooth, glossy or optically rough surfaces. It is distinguished in that a photometric stereo method, a deflectometric method and a scattering body (S) are combined so that the positions on the scattering body surface are two-dimensionally encoded.

L'invention concerne un procédé de détection de forme et/ou d'évaluation par voie optique de surfaces optiquement lisses, brillantes ou optiquement brutes. Ledit procédé se caractérise en ce qu'un procédé stéréoscopique, un procédé déflectométrique et un diffuseur (S) sont combinés de manière que les sites sur la surface du diffuseur soient codés en nappe.
