Abstract		This paper compares Fourier Transform Profilometry, a computer based technique for automatic 3-D measurement, with conventional Moire techniques. In Moire contouring techniques two gratings are used to generte Moire fringes. In contrast to that in FTP a grating pattern projected onto the object surface is Fourier transformed and processed. Results are analysed and some alternative test are presented. In addition to that an application in medicine is proposed for pulmonary function testing. Several measurements of lung relaxation pressure by observing the depression of skin between ribs have bee performed.
