Abstract
An improved phase algorithm for phase-measuring profilometry (PMP) is presented. In comparison with the traditional algorithms, it can remov e the influence of the carrier frequency before unwrapping and slow do wn the variation of the phase. This new algorithm makes the procedure of phase unwrapping easier and more automatic. it is especially suitab le for PMP with a high-frequency grating.
