  1. AO - Brainstorming Chair W. Gaessler

  2. AO in a Nutshell @J,H,K

  3. Discussion • Scientific wishes • On FoV • Performance • Site testing • AO correction in the visible • Seeing improvement only? • DecentStrehl: No believe? No interest? • IR wavefront sensor • Increase sky coverage • Multi object AO • Multiplexing • Does LUCIFERalready coverthis? • LGS for interferometer • Extreme AO

  4. K H J V I R Carbillet et al. 2004

  5. Summary of discussion • Phil Hinz emphasizes on IR WFS for LBTI • Schemes to extend the TT guide star exposure times by differential LGS TT measurments where discussed • A facility WFS with a dichroic instead of tertiary was proposed • Correction in the visible • The common response was to demonstrate first. • Possibly with the AGW acquisition camera • Field stabilization as at VLT for MODS and other instruments was suggested • Commen sensus on pushing for: • Sky coverage • Uniformity in field
