Integrated modeling approach for an active optics system

In all the new technology telescopes (medium, large, extremely large) the active optics is one of the most delicate systems. Sometimes only a perfect control of the mirrors can justify the whole telescope project. No assessed simulation tool exists, one of the reason is that the approach can be different for segmented or monolithic, medium or large mirrors, and so each telescope design staff usually develops its own simulation system. In this paper an integrated modeling approach is proposed, combining finite element analysis, dynamical systems simulation methods and optical performance analysis.
