Circularity measurement method
WebCircular fringe Fourier transform profilometry (CFFTP) based on a triangulation system has the capability of whole out-of-plane measurement using fewer fringes. To the best of our knowledge, the existing CFFTP [ 25, 26] calculates the displacement amount carrying the height information of the object by solving a quadratic equation.
