Paper Abstract

Using digital holography the two-source method was applied for shape determination of a groove on an Aluminum plate. The electric component of the electromagnetic field, on the image plane, was reconstructed using the Fresnel-Kirchoff integral and Fourier method and digital holograms were captured changing the fiber optic position with a micro positioner. The phase interferogram was filtered by means of the sine/cosine filter and for the unwrapping process was applied the branch-cut method. This object present real discontinuity and the experimental results agree with the expected one, with high quality intensity image. The quasi-3D phase presentation shows the object shape.
