Self-calibration in rotational shearing interferometry
Abstract
Diffraction-limited imaging of an incoherent object observed through fixed unknown aberrations is demonstrated using rotational shear interferograms. Reconstruction algorithms were inspired by radio-astronomy self-calibration methods. They require no reference point source other than the object itself to calibrate the effects of aberrations.
