AO4ELT4 Conference - October 26-30, 2015

The fourth bi-annual Adaptive Optics for Extremely Large Telescopes meeting took place in October 2015 at the UCLA Conference Center in Southern California. The theme of the meeting was AO systems and related instrumentation and the special challenges they face on extremely large aperture telescopes. The conference gathered specialists to review and discuss the latest developments of the ELT’s current design in terms of AO systems, related instruments and science goals. The conference also reported on pathfinder projects planned or implemented on existing telescopes, including solar telescopes, which provide relevant results for the next ELT’s design phase. Special attention is given to key components and new ideas that have the potential to overcome the limitations of existing systems, in order to increase the scientific impact of the future ELT’s.

Topic areas included:

  • Astronomy with AO on ELTs
  • Scientific observations with ELTs and related requirements for AO systems
  • Current designs for ELT AO systems
  • AO pathfinders & new ideas, including designs, lab testbeds, and on-sky experiments
  • AO numerical simulations and modeling
  • Wave-front sensors
  • Wave-front correctors
  • Laser Guide Star systems
  • System control & algorithms
  • Atmospheric turbulence and AO disturbance modeling and characterization
  • Data post processing and optimization, including PSF reconstruction, deconvolution, performance monitoring
