This paper describes a new phase extraction algorithm for phase profilometry. The algorithm uses a square wave to demodulate phase and moving averages and comb-shaped filters to extract the phase information from low-frequency. The proposed algorithm is compared with the two major profilometry techniques, namely Fourier domain profilometry and signal domain profilometry based on FIR low-pass filtering.
