Paper Abstract

In this work we have developed a design fringe projection method to obtain profilometry of a suitable object by using Dammann gratings encoded into an LCD as a modulator space and a monochromatic light source. Dammann grating are diffraction binary gratings commonly used to generate diffraction points with the same intensity in Fourier plane. Diffraction order and spatial frequency are parameter of grating design, several gratings types can be designed and projected on objects by controlling parameters of design.
