Scientific paper

An adaptive optics system for small to medium astronomical telescopes has been designed and is under construction. This adaptive optics system corrects the five lowest order Zernike wavefront aberrations, providing near diffraction-limited performance for telescope diameters smaller than about 5*r(subscript o), and useful correction up to about 10*r(subscript o). This adaptive optics system design consists of a lens-based wavefront aberrator, a CCD-based Shack-Hartmann wavefront sensor, and a personal computer-based feedback loop.
