Abstract

This paper presents an adaptive control scheme for adaptive optics. Adaptive compensation is needed in many adaptive optics applications because wind velocities and the strength of atmospheric turbulence can change rapidly, rendering classical fixed-gain reconstruction algorithms far from optimal. The paper also presents a method for generating frequency-weighted deformable-mirror modes, which are important for optimal performance of the adaptive control scheme. The performance of the adaptive control scheme is illustrated by simulations of a directed-energy system with a high-energy laser propagating through extended turbulence.
