Measuring surface shape by means of deflectometric reconstruction, a manifold of solutions is obtained if no additional knowledge can be employed. Though, whenever the object under consideration exhibits portions of diffuse reflection behaviour, uniqueness can be achieved by evaluating reflectance information. A set of characteristic curves in the image plane leads to a single surface point, from which the surface can be integrated thereafter. The practicability of our approach is demonstrated by the experimental results presented.
