Images reconstructed from intensity interferometry measurements of (top to bottom) a single, somewhat irregular elliptical “star”, a binary “star” with equal, and one with unequal components, from measurements with 100, 60, and 180 optical baselines, respectively. Sufficiently dense coverage of the interferometric Fourier-transform plane enables a reconstruction of the full source images, despite the lack of Fourier phase information. The scale on the right denotes relative intensities. In principle, the images are unique except for their possible mirrored reflections. These are believed to be the first diffraction-limited images that have been reconstructed from an array of optical telescopes, connected only through electronic software, with no optical links between them.
