Abstract

A 2D fringe pattern is designed and employed to perform 3D profile measurements by means of coaxial fringe projections and image acquisitions. To enhance the reliability and systematic accuracy, a signal processing algorithm is proposed as well. Accuracy of the retrieved 3D profile can be achieved in the order of sub-millimeters.
