Paper Abstract

Shape and deformation measurement by moiré topography or interferometry are introduced. By using the integrated phase shifting method proposed by the authors, shape measurements of various objects such as a hand with cell phone and a human face are performed in real-time. The integrated phase-shifting method can analyze the phase information of a projected grating on the object or an interferometric fringe pattern. The phase analysis provides the accurate shape of the object. The object is recorded by an NTSC-TV-CCD camera at 30 frames/second. The analyzed shape or flatness distribution is simultaneously displayed as a moving image of computer graphics. The analyzed shape is observed from any direction directed by a computer mouse in real-time.
