The capability of distinguishing fine details in simple structures by means of Fresnel domain diffraction is shown. Through numerical simulations it is shown that the bigger Fresnel's number in the diffraction considered the bigger differentiability is reached. A circular clear aperture with two fine details is employed for illustrating.
