Abstract

Adaptive Optics is an essential technology in today's large telescopes to compensate for atmospheric turbulence. Deformable Mirrors have many actuators(>10k), large stroke(>10mu), small spacing(100Hz).The well known use of piezoelectric ceramics has led to inappropriately stiff displacement actuators. However using force actuation, piezo's are superseded in performance, longevity and cost (factor 10-20 per channel).Regardless of the actuator type used, a model is presented for actuation of continuous facesheet mirrors to study its parameters. The model is validated using finite element simulations and is used to derive design fundamentals for optimization.
