From these the interferometric methods are characterized by accuracies up to the nanometer- range which is only of interest for the inspection of high-precision parts. With respect to specifications of typical automobile components micrometer-accuracies are aufficient. Suitable laser-based contour measuring techniques are presented in this paper.encross sectionfringe projectioninterferometric methodmicrometer-accuracyshapetriangulationworkpiece621conference paper
