The first success- ful laboratory test of TPs in 2003 suggested that these de- vices could represent a viable approach to achieve super- resolution in Radio Astronomy. We have therefore started a project devoted to an exhaustive study of TPs and how they could be implemented on a radio telescope. In this work we present a summary of the design and laboratory tests of an optical module based on TPs that we plan to field-test on the Medicina 32-m radio telescope.ELETTRONICOenConference paper10.23919/URSI-AT-RASC.2018.84715252-s2.0-85051939771http://www.ursi.org/proceedings/procAT18/papers/paperATRASC2018v2.pdfhttps://ieeexplore.ieee.org/document/8471525FIS/05 - ASTRONOMIA E ASTROFISICA
