  6. AO-WP Management 1st generation AO & MCAO design for ELTs Large format, high Density DMs R&D 100m-Layer WFS exp. Novel AO concepts AO & MCAO simulations Algorithms for reconstruction & control A European AO Roadmap: I- Why? • develop next generation AO facilities for the 8-10 m.(VLT, LBT, GTC) • and AO enabling technology for the European ELT • fully using their many commonalities • within European-wide collaboration programs • OPTICON for 1st phase R&D (5.75 M€ EC AO funding) • ELT Design Study for 2nd phase (5 M€ AO requested to EC) • and extensive collaborations with North-America(AURA-ESO MOU, ESO-CfAO & more)

  8. MAD Rayleigh AO demonstrator 2Q ‘05 WHT FALCON (OPM) 1st closed loop end April ‘04 A European AO Roadmap: III- What? • Advance/refine concepts for ELT AO Systems • AO concepts: XAO-GLAO-MCAOs • Laser concepts: PIGs (R. Ragazzoni) • Objects (Science & Reference Stars) picking concepts • Start 1st generation of scalable AO building blocks • Laser Guide Star Systems (emitter + projector) • Deformable Mirror Systems (DM + command) • Visible & IR WFS Systems (detector + controller) • Real-Time Computation Systems (HW & SW) • Data Reduction/Analysis Systems (algorithms & DUI)

  10. PASS- LLNL Hyper-Telescope(Labeyrie et al.) ELPOA ADAPTIVE OPTICS IN EUROPE R. Foy et al. A next generation path to avoid T/T stars Adaptive Optics in Europe

  11. A European AO Roadmap: III- What? • Ensure adequate supporting Infrastructures • C-based Intelligence (trained AO Specialists & Scientists) • Si-based Intelligence (e.g. simulation farms)

  12. Sqrt stretch FWHM ~ 5 mas Sr (K)~ 30% SIMULATION TOOLS: OWL MCAO in NIR NGS 1 2’ FOV 100m - K band NGS 3 Object 2 DM (9k act.) 3 NGS Strehl (K) NGS 2 Time

  13. A European AO Roadmap: III- What? • Ensure adequate supporting Infrastructure • C-based Intelligence (trained AO Specialists & Scientists) • Si-based Intelligence (e.g. simulation farms) • Laboratory benches & test equipments

  14. High DM Low DM DM Vector Time Durham MCAO Lab • 2 layer evolving turbulence generator based on holographic liquid crystals • 2 WFC adaptive optics system based on 37-actuator modal LC devices • Shack Hartman Star Oriented Control Loop • ~1 Hz open loop bandwidth • 5 artificial guide stars Similar kind of facilities @ MPIA-Heidelberg, OPM, ESO ….

  15. SLODAR Cn2(h) profiler MASS-LITE turbulence profiler Coll. With AURA-CTIO In use @ La Palma since April ‘03 A European AO Roadmap: III- What? • Ensure adequate supporting Infrastructure • C-based Intelligence (trained AO Specialists & Scientists) • Si-based Intelligence (e.g. simulation farms) • Laboratory benches & test equipments • Site characterization AO instruments

  16. A European A.O. Roadmap: Conclusions • 1st good news: substantial A.O. resources in Europe • 2nd good news: coordinated R&D with  EC funds • 3rd good news:  cooperation with North-America • A sobering thought: our common “insane” ambitions a Wish … or a Prediction? A.O. for ELTs may become a show-slower but will not be a show-stopper!
