| Abstract: | The phase unwrapping is a significant and difficult procedure for profilometry based on fringe. A new algorithm based on coded phase is proposed in this paper. It identifies the order of the fringe by projecting fringes with coded phase onto the object and performs fast phase unwrapping. The computer simulation and the experiment are presented to prove the feasibility and validity of the new algorithm. |
