Windowed Fourier ridge algorithm has been proposed for fringe pattern analysis. However, this algorithm produces a bias in the retrieved phase. In this paper, a method is proposed to correct the phase bias. The second order derivatives of the phase are estimated by using two frequency points and then used to compensate the phase. By testing the method on a simulated fringe pattern, improvement by the proposed phase compensation method is shown.
