Dr Heejoo Choi On Large Astronomical Optics

The Spotlight Report

This month Dr. Heejoo Choi sat down to discus active and adaptive optics measures utilized in a range of astronomical telescopes. Specifically, Dr. Choi’s work brings him into frequent contact with a unique subset of astronomical optics known as ‘extremely large telescopes’, which are designated as having a clear aperture larger than 10 meters. Dr. Choi explains what some of the tools and devices are that allow for keeping such massive optics and structures aligned throughout long exposure sessions and in variable environments.
