Hilbert assisted wavelet transform method of optical fringe pattern phase reconstruction for optical profilometry and interferometry

A Hilbert assisted wavelet transform (HWT) method is presented for phase reconstruction of 3D profilometry and interferometry. A rigorous mathematical demonstration about this HWT method is given in this paper. An important conclusion that the phase of the optical fringe pattern is equal to the phas...
