Abstract

The transient response of a deformable mirror to be used in a closed-loop adaptive-optics imaging system is modeled and evaluated. A theoretical model is developed that describes the motion of the mirror membrane. This allows an adaptive control to achieve reduced overshoot and short settling time. Applicability of the model is tested on a mirao 52-e electromagnetic deformable mirror using a specially designed highspeed adaptive-optics test bench. This test bench permits precise mirror motion measurements up to 10 kHz.
