Woofer Tweeter Status

• Optical alignment is done
• The computer and software architecture is ready
• Most of he control algorithms have been written and validated with simulation
• All the hardware components are now integrated on the bench
• Preliminary simulation and validation against real hardware in progress
• Characterization of deformable mirrors is in progress

Woofer Tweeter Plan

• For September/October 2005:
  • Woofer and tweeter integration
  • WFS, tip-tilt, woofer and tweeter calibrations and tests
  • First closed-loop runs (without the real-time pipeline)
• Until January-February 2006
  • Real-time closed-loop runs with the different control algorithms and final report

Woofer-Tweeter follow on tests

• MCAO upgrade:
  • Conjugation of the woofer in altitude
  • Test of MCAO control algorithms (tomographic reconstruction)
• High order tweeter upgrade:
  • Tests in true condition of control algorithms for XAO and MCAO with ELTs
