Commonly, the 3D surface reconstruction is done by analyzing the deformation of the image of binary grating projected onto the relief of an opaque object. The phase of the deformed grating is extracted by Fourier transform and unwrapping the phase by some algorithm. One technique to image grating projection is the Talbot effect that creates self-images of a periodic objects. In this work, one of the self-images is used to be transmitted through a phase object. The difference in thicknesses of the transparent object causes a change in the optical path length of the light beam and deforms the grating lines. This deformation is analyzed to find the 3D shape of this object. Some experimental results are shown.
