Paper Abstract

A new method for analyzing the phase distributions of carrier fringe pattern has been presented. The discontinuities and spurious data has been and still is a cumbersome concern, it is hard to reconstruct the phase by phase demodulation based on phase gradients. The approach that we here introduce to solving this problem is to utilize Gabor transform, a tool excelling for its multiresolution in space-frequency domain, to analyze the phase distributions. The experimental results demonstrate the validity of the proposed method.
