Visual Acuity and Spatial Modulation Thresholds

  • Chapter
Visual Psychophysics

Part of the book series: Handbook of Sensory Physiology ((1536,volume 7 / 4))

Abstract

Seeing shapes and patterns is the major capacity inherent in our visual system. It depends, to be sure, on the ability to distinguish differences in light intensity and color, but this is not enough; they must be distinguished more or less simultaneously and identified as belonging to different areas of the visual field. Ultimately all this raises the question of the kind of spatial divisibility or capacity for spatial partitioning exhibited by the visual system. When taken to the limit of sensory threshold, this becomes the traditional topic of visual acuity or spatial resolving power of the visual apparatus.
