Performance
Scientific paper
This paper presents modeling and simulation results pertaining to the wave front correction performance of the recently developed large aperture deformable mirror concept using the novel flexure-hinged substrate. The modeling addresses the potential of this new concept to significantly alleviate the CTE mismatch problems, thereby opening the door to greatly relaxed fabrication, thermal and operational requirements of telescopes. The large aperture deformable mirror consists of an ultra-lightweight nanolaminate face sheet supported by actuated flexure-hinged lightweight substrate. The mirror system is modeled using a combination of Matlab and NASTRAN codes. Using this model, mirror responses to severe thermal loads and the corrections of the resulting deformations through the actuated substrate, are studied. These results represent an important first step in advancing this new concept towards eventual laboratory tests.
