" Adaptive Optics at the MPIA - From ALFA into the NIRVANA "
Sebastian E. Egner (MPIA)
The Max-Planck-Institute for Astronomy in Heidelberg, Germany
(MPIA) first got involved in Adaptive Optics for Astronomy in
the early 1990s with a tip/tilt secondary for the UKIRT and the
ALFA system for the 3.5m telescope on Calar Alto. Ever since
then, the MPIA has been involved in various AO instruments and
LGS facilities for Calar Alto, the VLT, and the LBT. I will give
a short overview of past, current and future instruments developed
at the MPIA in the context of Adaptive Optics. Then I will focus
on two particular projects, which I have been involved in over the
last few years. The first project is a site characterization campaign
with a SCIDAR of Mt. Graham, the site of the LBT, to determine the
vertical profile of the atmospheric turbulence. The second project
is to characterize a prototype of the layer-oriented MCAO system of
LINC-NIRVANA in closed-loop operation. As an outlook I would like
to show some areas for a future collaboration between Subaru and
MPIA related to Adaptive Optics instrumentation.
