Abstract

Burtt and Catton suggested that insects can resolve striped patterns finer than the theoretical limit set by the small diameter (30 microns) of the ommatidial lenslets. Events at the edges of the window behind which the patterns are moved explain these experiments without transgressing diffraction limitations. This interpretation leads to successful quantitative predictions of the effects of changing the boundary conditions.
