In recent years, intensity interferometry has seen renewed interest and successful application at Imaging Atmospheric Cherenkov Telescope arrays such as H.E.S.S., MAGIC and VERITAS. However, these measurements can only be performed during bright moon periods while the instruments' primary purpose---gamma-ray observations---cannot be fulfilled, the Mobile Intensity Interferometer for Stellar...
The Multi-Aperture Spectroscopic Telescope (MAST) is a modular array of 20 × 60 cm telescopes currently being commissioned at the Weizmann Astrophysical Observatory in the Negev desert, Israel. Designed primarily for astronomical spectroscopy, MAST employs a novel fiber-fed architecture in which each on-axis beam is collected by an optical fiber and delivered to the object plane of a dedicated...
The simultaneous record of photons with at least three telescopes not only allows traditional two-photon correlations between pairs of telescopes, but also to explore three-photon correlations in the telescope triangle. Such measurements in principle enable measurements of the (cosine of the) closure phase, the sum of the interferometric phases in the triangle, and by that retrieve at least...
