Abstract: This invention discloses using one or more color-encoded fringe patterns for optically, three-dimensionally measuring an object's shape. In one embodiment, a color-encoded fringe pattern comprising a plurality of fringes that are modulated in intensity is configured as follows. An individual fringe selected from the fringes comprises a colored line at a location on the fringe width. The colored line has a line width that is substantially narrower than the fringe width in order that the colored line has a substantially similar intensity over the line width. The individual fringe excluding the colored line has a fringe color that is substantially uniform over the individual fringe. The fringe color is substantially different from the line color. Fringe colors of all the fringes are substantially similar, thereby enabling a major portion of the color-encoded fringe pattern to provide a substantially-uniform illumination color for projection onto the object.
