Query: I3T: Intensity Interferometry Imaging Telescope   We propose a new approach, based on the Hanbury Brown and Twiss intensity
interferometry, to transform a Cherenkov telescope to its equivalent optical
telescope. We show that, based on the use of photonics components borrowed from
quantum-optical applications, we can recover spatial details of the observed
source down to the diffraction limit of the Cherenkov telescope, set by its
diameter at the mean wavelength of observation. For this, we propose to apply
aperture synthesis techniques from pairwise and triple correlation of sub-pupil
intensities, in order to reconstruct the image of a celestial source from its
Fourier moduli and phase information, despite atmospheric turbulence. We
examine the sensitivity of the method, i.e. limiting magnitude, and its
implementation on existing or future high energy arrays of Cherenkov
telescopes. We show that despite its poor optical quality compared to extremely
large optical telescopes under construction, a Cherenkov telescope can provide
diffraction limited imaging of celestial sources, in particular at the visible,
down to violet wavelengths.
