Abstract

-In a recent published work we proposed a technique to recover the absolute phase maps of three sets of fringe patterns with selected wavelengths. It is demonstrated that the absolute phase maps can be unwrapped from the wrapped phase maps by the three-step phase-shifting profilometry (PSP), using only 9 fringe patterns. However, few incorrect values still remain in the recovered absolute phase. In this paper, we develop a method to correct and remove the errors in the recovered absolute phase. The experiments validate the effectiveness of our proposed method.
