    "abstract": "While adaptive optical systems are able to remove moderate wavefront\ndistortions in scintillated optical beams, phase singularities that appear in\nstrongly scintillated beams can severely degrade the performance of such an\nadaptive optical system. Therefore, the detection of these phase singularities\nis an important aspect of strong scintillation adaptive optics. We investigate\nthe detection of phase singularities with the aid of a Shack-Hartmann wavefront\nsensor and show that, in spite of some systematical deficiencies inherent to\nthe Shack-Hartmann wavefront sensor, it can be used for the reliable detection\nof phase singularities, irrespective of their morphologies. We provide full\nanalytical results, together with numerical simulations of the detection\nprocess.",
