Paper Abstract

We demonstrate how to correct odd-order aberrations (tilt, coma, etc.) of the imaging system on the basis of information containing in the phase transfer function. For earth- observation systems this information can be obtained just by accumulation of the detected images, without source of the reference beam or wavefront detector. This technique is beneficial for elaborating robust equipment for long-term operation in autonomous conditions.
