Abstract

A signal processing algorithm is presented for 3D profile measurements by means of coaxial fringe projections. It helps to reduce the noise caused by low reflectance and enhance the systematic reliability. Accuracy of the retrieved 3D profile can be achieved in the order of sub-millimeters.
