2014 Caltech Ground-layer Adaptive Optics Workshop

The science motivation and technological solutions for ground-layer adaptive optics (GLAO) are maturing rapidly. Improved seeing over moderate field of view (arc minutes) holds the potential to reinvigorate existing, substantial investments in 5-10 meter telescope instrumentation.

This informal mini-workshop will explore the motivation and potential implementations of GLAO. Discussions will be free-form and new ideas and interchange are welcome.

Date and Time Session 1 Sunday 14 Sept 2014 2p-5p Overview and Science
Session 2 Monday 15 Sept 2014 9a-4p Implementation and Strategy
Location: Hameetman Auditorium Cahill Center for Astronomy and Astrophysics, Caltech
Dial-in: 866-675-1191 x8203140
Polycom IP: 131.215.193.38 (by request only - expecting Wizinowich and Lacy on Polycom)

Workshop Goals

  • Scientifically motivate an assessment of GLAO opportunities
  • Review the technical maturity and competitive landscape for GLAO-augmented science in the coming decade
  • Review the best turbulence measurement statistics for Mauna Kea
  • Review detailed performance modeling to assess the scientific potential of GLAO on 2.2 - 30m telescopes
  • Assess the technical maturity and demonstrated performance of adaptive secondary mirrors
  • Bring together parties interested in the future of GLAO on Mauna Kea
