Abstract
We present the results of the amplitude diffraction pattern produced by two circular apertures. It was found that on the Fraunhofer plane there are is a diffraction pattern with an elliptical geometry with a Bessel-like spatial distribution modulated by Young fringes. The model was experimentally confirmed using circular apertures illuminated with a Helium-Neon laser and propagating to either the divergent Fresnel zone and the Fraunhofer plane using an achromatic cemented doublet as transforming lens.
