Abstract
Correction of the influence of phase corrugations in the pupil plane is a fundamental issue in achieving high dynamic range imaging. We present here an imaging system which, thanks to non-redundant pupil remapping and spatial filtering, allows a perfect determination of the Optical Transfer Function. We do show that such a system would allow image reconstruction free from phase perturbations, photon noise limited, and with high dynamic range.
