Abstract: Abstract To analyze the influence of the thin-film residual stresses on the high-order aberrations of deformable mirrors, a finite-element model of a 37-element deformable mirror was constructed. The deformation and high-order aberrations were simulated after… read more here.

Abstract: This paper discusses the shape control of deformable mirrors for Adaptive Optics in the dynamic range. The phenomenon of control-structure interaction appears when the mirror becomes large, lowering the natural frequencies fi, and the control… read more here.
