Toraldo Pupils represent a viable approach to achieve super-resolution on antennas and radio telescopes. In this work we present a summary of the electromagnetic simulations and laboratory tests of a prototype optical module based on a Toraldo Pupil that has been field-tested on the Medicina 32-m radio telescope.ELETTRONICOenConference paperhttp://www.elettromagnetismo.it/wp-content/uploads/2018/09/XXII-RiNEm-Conference-Proceedings.pdfhttps://sites.unica.it/rinem2018/FIS/05 - ASTRONOMIA E ASTROFISICA
