Abstract / Description:The AO department of ESO has completed the
design of an adaptive AO system for the VLT
Interferometer. Ordering of components,
manufacturing and integration took place in 2001
and 2002. The system is built in four copies, one
for each VLT. It is installed at the Coudé room
and the Coudé train is used as a "science path".
Only one of the mirrors (M8, pupil conjugated) is
replaced by the corrective optics. The 60
elements system should allow a Strehl ratio of
~0.6 on bright sources. Commissioning activities
started in April 2003 and the delivery of the 4th
system is planned for late 2004. At the time of
this writing the first commissioning of the first
MACAO has been completed and results are
encouraging. The integration and test phase of
the 2nd system is in full swing.
