Fringe projection is one of the established background procedure for contactless optical 3D surface measurement based on geometrical triangulation of corres-ponding image points. It is used to generate phase values which identify corresponding points. Fringe generation may be realized by conventional digital (DMD, LCoS) or by classical slide projection. However, recent developments provide the chances to use particular equipment to obtain certain advantages. The use of a tailored free-form mirror (FFM) for phase shifted fringe generation is such an unusual hardware for a 3D scanning system which was developed at our institute.
