Photonics Focus Magazine Vol. 1 Issue 3

May/June 2020 | Vol. 1 | Issue 3
Space from the Ground

This issue of Photonics Focus explores the tools and systems that modern astronomers use to study space from the ground. Two feature articles explain different methods to create ever-larger telescope mirrors: spin-casting monoliths, and segmentation with adaptive optics. Another article reveals the enormous challenge of building highly precise instruments in some of the most seismically unstable locations on Earth; and yet another tells the story of the unfathomable amounts of data that will be generated by modern instruments, and how scientists plan to manage it.

Select articles are available online, but the complete issue is available for download as a PDF.
