To carry out a wide range of high-spatial resolution observations, it can combine the two AO-corrected 8.4-m apertures of the LBT in various ways including direct (non-interferometric) imaging, coronagraphy (APP and AGPM), Fizeau imaging, non-redundant aperture masking, and nulling interferometry. It also has broadband, narrowband, and spectrally dispersed capabilities. In this pa","authors_text":"A. Puglisi, A. Skemer, A. Vaz, B. Mennesson, D. Defr\\`ere, E. Downey, E. Spalding, J. Eisner, J.
