Image Sharpening by Holography
Greatly sharpened images may be extracted from photographs which have been blurred either by accident or by unsurmountable instrumental imperfections. In simple words, it has recently become truly possible to turn a bad photograph into a good image in a great number of situations, including cases when photographs were blurred by motion, imperfect focus,atmospheric turbulence and by instrumental defects(including aberrations) among other causes.
