This paper describes early results of a theoretical investigation of the performance of an adaptive optics system in which a limited number of Karhunen-Loeve modes of the wavefront distortion are corrected. We have determined the on-axis point spread function for an idealised adaptive optics system in Kolmogorov seeing, whose performance is defined in terms of radii of included energy and Strehl ratios for a range of examples. We discuss extensions of the analysis for the off-axis point spread function, and for non-Kolmogorov seeing.
