Soh Kam Yung"[Researchers] developed a system that uses multiple laser beams to illuminate a distant target and uses a pair of small telescopes to collect the reflected light. The team demonstrated that this intensity interferometer can image millimeter-wide letters at a distance of 1.36 km, a 14-fold improvement in spatial resolution compared with a single telescope."<a href="https://physics.aps.org/articles/v18/99" rel="nofollow noopener" translate="no" target="_blank">https://physics.aps.org/articles/v18/99</a><a href="https://mstdn.io/tags/Lasers" class="mention hashtag" rel="nofollow noopener" target="_blank">#Lasers</a> <a href="https://mstdn.io/tags/Telescopes" class="mention hashtag" rel="nofollow noopener" target="_blank">#Telescopes</a> <a href="https://mstdn.io/tags/Interferometry" class="mention hashtag" rel="nofollow noopener" target="_blank">#Interferometry</a> <a href="https://mstdn.io/tags/Physics" class="mention hashtag" rel="nofollow noopener" target="_blank">#Physics</a> <a href="https://mstdn.io/tags/Optics" class="mention hashtag" rel="nofollow noopener" target="_blank">#Optics</a>
