Investigation and Theoretical Interpretation on Hyperacuity

Hyperacuity is a peculiar phenomenon in vision. Firstly, this paper introduces the term "hyperacu ity" and describes systematically the experimental results,then briefly summarizes the related theories and models. From the point of view of information theory, the paper points out that hyperacuity is a functional phenomenon at systematic level. Theoretical implications and the possibilities of hyperacuity application are also discussed.
