| Citation | He has made diverse and important discoveries about the visual system over the past 30 years. These include the mathematical analysis of disjunctive eye movements as a control system - an analysis with the greatest predictive power so far achieved on a biological system of this type; objective determination of the quality of the retinal image; the influence of the cerebellum on eye movements in primates; the mechanism for achieving high positional accuracy in vision (hyperacuity) and the reasons for the small effect of image motions on this ability. His work is respected for its reliability, diversity, and the depth of its analysis. He is internationally regarded as the leading exponent of physical methods in the analysis of vision. |
