1 December 1991 Anisoplanatism and the use of laser guide stars

The effects of focal and angular anisoplanatism are computed in order to evaluate the utility of using a single laser-produced guide star for the correction of ground-based astronomical imaging. The equations for the calculation of these effects are derived and the performance of a sodium-layer laser guide star system is computed for a Hufnagel atmospheric turbulence model. These results are presented in scaled units and for selected telescope apertures from 2-8 m in diameter operating at wavelengths from 0.5 to 2.0 microns. The limiting telescope aperture size which can be adequately corrected using a single sodium-layer guide star is shown to be much larger than previously estimated.
