Description
Intensity interferometry is a technique similar to conventional amplitude interferometry, except that it is insensitive
to atmospheric turbulence and that it does not require good optical quality of the telescope system. Therefore arrays of Imaging Atmospheric Cherenkov Telescopes can be (and since a few years are) used to measure the angular sizes of stars and star systems. We report from the first two Intensity Interferometry campaigns at the H.E.S.S. gamma ray observatory in 2022 and 2023.
