Paper Abstract

Design considerations and working formulas and graphs are presented for estimating the actuator requirements for adaptive optics correction of global tilt and residual piston error arising from atmospheric turbulence along a ground-to-space path. Frequency characteristics are calculated for several important crosswind conditions for the case where the active segments are very small compared to the full aperture; it is shown that the velocity profile has a strong effect on the power spectra and that high slew rates significantly increase the required high-frequency response and accentuate the effects of high-altitude turbulence. Predictions are given for the SELENE laser power beaming system which uses active control of a segmented primary telescope mirror.
