Paper Abstract

A phase unwrapping method by spatially encoding the fringe patterns is presented for phase-shifting projected fringe profilometry. For spatially isolated objects or surfaces with large depth discontinuities, unwrapping can be identified without ambiguity. Even though the surface color or reflectivity varies rapidly with position, it distinguishes the fringe order accurately.
