Optical non-contact 3D profilometry of the palate in subjects with cleft lip and/or palate

Within the framework of a research project concerning hard palate morphometry in facial clefts, optical non-contact 3D profilometry based on the Fourier transform method was applied. The article discusses the principle of Fourier transform profilometry, the procedure for image acquisition and processing, as well as the merits of this method in the study of palate morphology.
