Abstract

A new technique of the fringe analysis is proposed to automatically measure the 3D object shape. A grating pattern is projected onto an object, and the grating pattern deforms in accordance with the 3D object. This deformed grating image is analyzed by means of subfringe integration algorithm, the phase distribution and the object shape are given at every pixel at measured object. In contrast to FOurier transform profilometry (FTP), this technique processes fringe in its spatial domain instead of the frequency domain, so it is faster and more convenient than FTP.
