Abstract

In the present work we present a simple comparative analysis of the results in the optical Fourier transform profilometry which fringe projection is produced by two different methods, dynamic moiré-like patterns and Michelson interferometer. First, the Fourier transform profilometry technique is applied in the projected moiré fringe pattern onto an object surface. Then, this result is compared to the Michelson fringe pattern projection in the same method of profilometry that is applied using the same test object. We have conclude that dynamic moiré-like fringe patterns could be used with some advantages, comparatively to the results obtained by the classical Michelson fringe patterns.
