摘要：

The optical profilometry techniques have become more and more used in dynamic 3-D shape measurement. In particular, there are two problems to overcome. One is to recover the phase from a single fringe. The second problem is the phase recovering from a pattern avoiding that the harmonics introduced by the projector. In this work, we analyzed two kinds of techniques: off-axis and slightly off-axis interferometry algorithms for phase retrieval. The Hilbert transform is implemented in both cases. Validation experiments are presented.
