Paper Abstract

In this work, we present the results obtained in the laboratory when diffraction images are observed, produced by a Ronchi ruling, of a flat circular object, objects with a periodical structure, like for example screws, and masks, with certain regular structure. The diffraction images of these objects are processed by a computer program in order to determine important characteristic of them, for instance: the measurement of the diameter of a hole, the measurements of the profile of a screw, and the periodicity of the structure of square masks.
