" New generation Subaru LGSAO System: Mechanical behavior of Deformable Mirror 188 "
Aurelien Bouvier (SUBARU Telescope)
Adaptive Optics System is now a key component of large ground-based telescopes regarding high resolution imaging.
The Subaru AO team is currently building a new generation AO System that should have its first light in March 2006.
Ultimately, a Laser Guide Star system will be added (first light: March 2007).
I will first review the characteristics and performances of this system.
Then I will focus on one of its key component: a Deformable Mirror made of 188 control elements, the largest bimorph mirror ever built.
We will go through its mechanical behavior and see some limitations caused by its dynamic response that lead to my work on a damping system for the DM188.
