Abstract

We report experimental results for what we believe to be a new technique for estimating aberrations that extends the strength of an aberration that may be sensed with Hartmann sensor technology by means of an algorithm that processes both a Hartmann sensor image and a conventional image formed with the same aberration. We find that the theory and the experiment match well within the experimental error and that strong defocus aberrations can be accurately sensed with this technique.
