  • Method and apparatus for the three-dimensional measurement of the shape and the local surface normal of preferably specular objects
    Patent number: 8284392
    Abstract: An apparatus and a method permit the 3D detection of specular objects which are transparent to visible light. The method operates on the basis of the principle of deflectometry with specific improvements.

  • Method and apparatus for determining the shape and the local surface normals of specular surfaces
    Patent number: 7532333
    Abstract: A method teaches how to measure—even strongly curved—specular surfaces with an apparatus that measures a shape as well as local surface normals absolutely. This is achieved by the observation and evaluation of patterns that are reflected at the surface. The reflected patterns are observed from different directions. The evaluation is done by termination of those locations in space, where the surface normals that are observed from different directions, have at least deviations against each other.

  • Method and Apparatus for Three-Dimensional Measurement of Objects in an Extended angular range
    Publication number: 20080074648
    Abstract: An apparatus and a method are presented which render possible the 3D acquisition of objects (4) with the aid of an optical 3D sensor from an angular range that is larger than that which is yielded by one view, in a short measuring time and without mechanical movement. This end is served by a specific mirror arrangement (3) in combination with a modification of the optical 3D sensor.
