Paper Abstract

Wave-front reconstruction from defocused stellar images has now been widely applied to the testing of ground-based optical telescopes. We describe here the latest improvements to the technique and discuss how to reach a maximum accuracy. Statistics are given on the aberrations observed over 10 different telescopes.
