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.
