Abstract
Greatly sharpened images may be extracted from photographs which have been blurred either by accident (motion, imperfect focus, atmospheric turbulence, etc. ) or deliberately, for instance when 'coded' in view of special image processing or synthesis applications. Four image deblurring methods may be distinguished: I. Coherent optical analogue processing, 2. Incoherent optical analogue processing (non-electronic ), 3. Incoherent opto-electronic analogue processing and 4. Digital computer processing. A general review of the field may be found in reference (1). In this paper, we give a brief review of the principles of the holographic image deblurring methods, originated by the author with students in 1967, and now implemented in a number of forms, all of which appear to indicate that this method of coherent optical analogue image processing is probably the most powerful image-deblurring method at this time, notably in view of high-resolution image-restoration applications.
