Abstract

A phase unwrapping method based on the phase-wedged encoding algorithm for phase-shifting projected fringe profilometry is presented. The patterns used to perform the phase-shifting technique can be used for unwrapping directly. Even though the size of the inspected objected is so small that only one fringe is projected, fringes can be discerned correctly.
