Adaptive cross-correlation algorithm for extended scene Shack-Hartmann wavefront sensing.
We present an adaptive cross-correlation algorithm for a large dynamic range extended-scene Shack-Hartmann wavefront sensor. We show that it accurately measures very fine image shifts over many pixels under a variety of practical imaging conditions.
