Diffraction-limited imaging of unknown objects through fixed unknown aberrations using interferometry.
Abstract
Diffraction-limited imaging of unknown objects through fixed unknown aberrations is demonstrated using rotational shear interferograms. Objects are assumed to be fully incoherent. No reference point source is used to calibrate the effects of aberrations. Several algorithms are described, and two are successfully used to reconstruct extended objects. Best results are obtained by combining the two successful ones.
