Highest resolution imaging in astronomy is achieved by interferometry, connecting telescopes over increasingly longer distances and at successively shorter wavelengths. Here, we present the first diffraction-limited images in visual light, produced by an array of independent optical telescopes, connected electronically only, with no optical links between them. With an array of small telescopes, second-order optical coherence of the sources is measured through intensity interferometry over 180…

Optical Intensity Interferometry through Atmospheric Turbulence
Conventional ground-based astronomical observations suffer from image distortion due to atmospheric turbulence. This can be minimized by choosing suitable geographic locations or adaptive optical
Synthetic Aperture Imaging in the Optical Domain
The wave-like properties of photons gives rise to diffraction, or the bending of waves when passing through an object or an aperture. Diffraction limits the resolution of an aperture, with larger
Development of a digital astronomical intensity interferometer: laboratory results with thermal light
Abstract We present measurements of the second-order spatial coherence function of thermal light sources using Hanbury-Brown and Twiss interferometry with a digital correlator. We demonstrate that
Attosecond precision multi-kilometer laser-microwave network
TLDR
This work realizes a complete laser-microwave network with 950-attosecond timing jitter for 18 h, which can enable next-generation attosecond photon-science facilities to revolutionize many research fields from structural biology to material science and chemistry to fundamental physics.
