- W2081103467 abstract "The employment of adaptively controlled segmented mirror architectures has become increasingly common in the development of current astronomical telescopes. Optomechanical analysis of such hardware presents unique issues as compared to that of monolithic mirror designs. Performance analysis issues include simulation of adaptive control, execution of polynomial fitting, calculation of best fit rigid body motions, and prediction of line-of-sight error. The generation of finite element models of individual segments involves challenges associated with correctly representing the geometry of the optical surface. Design issues include segment structural design optimization and optimum placement of actuators. Manufacturing issues include development of actuation inputs during stressed optic polishing. Approaches to all of the above issues are presented and demonstrated by example with SigFit, a commercially available tool integrating mechanical analysis with optical analysis." @default.
