Abstract
Toraldo Pupils (TPs) can improve the angular resolving power of an optical instrument beyond the classical diffrac- tion limit (hence the term super-resolution) using a filter consisting of finite-width concentric coronae with differ- ent amplitude and phase transmittance. 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.
