Is it possible to achieve an optical resolution greater than that predicted by the Rayleigh criterion? The term "super resolution" conjures up visions of defeating the law of diffraction, which would rank right up there with abandoning the uncertainty principle. But, resolution can be increased under certain circumstances. The path to understanding super resolution lies in combining the concepts of noise and information ( some apriori knowledge of the object) with diffraction to mold a comprehensive theory of optical resolution.
