Abstract: There has been a recent interest to revive optical Stellar Intensity Interferometry (SII) using Imaging Air Cherenkov Telescope (IACT) arrays. Planned arrays containing nearly 100 telescopes, and separated by up to 1 km, will provide a dense sampling of the (u, v) plane. This will enable the implementation of recent developments in phase retrieval techniques for model-independent image reconstruction. Simulations indicate that sub-milliarcsecond features as well as temperature differences of the order of a few hundred K can be imaged. An overview of the imaging capabilities of IACT arrays used as intensity interferometers at short (λ ≈ 400 nm) wavelengths is presented.
