Abstract
The self-imaging phenomenon of a square wave binary amplitude grating is studied. The intensity distributions in the Fresnel diffraction image planes lying at distances z = (M -1/4)d 2/u from the grating illuminated by a plane wave are calculated. It is found that these images are very similar to the object structure. As a consequence, some potential applications are proposed.Keywords
