In this paper we are concerned with the elimination of gamma related errors by employing a simple and direct approach, specifically, for phase measuring profilometry (PMP) methods. The harmonic structure of a gamma distorted fringe is investigated and the implications of j for the PMP algorithm is studied. The minimum requirements in terms of number of Steps for appropriate elimination of j related phase residuals is identified and verified via both simulation and practical experimentation.
