Paper Abstract

This paper discusses the application of adaptive control methods in the Atmospheric Simulation and Adaptiveoptics Laboratory Testbed at the Starfire Optical Range at the Air Force Research Laboratory, Kirtland AFB. Adaptive compensation is useful in adaptive optics applications where the wavefronts vary significantly from one frame to the next or where wind velocities and the strength of atmospheric turbulence change rapidly, rendering classical fixed-gain reconstruction algorithms far from optimal. The experimental results illustrate the capability of the adaptive control scheme to increase Strehl ratios and reduce jitter.
