Abstract :

[en] The Large Binocular Telescope Interferometer (LBTI) is a strategic instrument of the LBT designed for high-sensitivity, high-contrast, and high-resolution infrared imaging of nearby nearby planetary systems. It combines the two 8.4-m apertures of the LBT in various ways including direct (non-interferometric) or Fizeau imaging, non-redundant aperture masking, and nulling interferometry. First fringe-tracked observations were obtained in December 2013. We report in this paper on the status and recent progress of the LBTI with a particular focus on interferometry.
