Shack–Hartmann sensor: An instrument that divides an incoming wavefront into multiple subapertures to analyse local tilts and reconstruct the overall phase.

An important factor which affects performance of solar adaptive optics (AO) systems is the accuracy of tracking an extended object in the wavefront sensor. The accuracy of a centre-of-mass approach to ...
