Abstract

A hybrid optical-digital image processing system is developed for deblurring out-of focus pictures. The optical part is a dual-channel non-coherent processor which implements the Wiener filter for deblurring through appropriate pupil functions. The methods of implementing the bipolar PSF in a non-coherent processor are described, as are the methods of determining the pupil functions from the given PSFs. The digital part of the processor subtracts or demodulates the outputs from the dual channel optical processor to give the final deblurred picture. The pupil functions are experimentally realized and the deblurred outputs are presented.
