Application of fourier analysis to the visibility of gratings

Open access
Campbell, F. W., Robson, J. G.·1968·The Journal of Physiology

Abstract

1. The contrast thresholds of a variety of grating patterns have been measured over a wide range of spatial frequencies. 2. Contrast thresholds for the detection of gratings whose luminance profiles are sine, square, rectangular or saw‐tooth waves can be simply related using Fourier theory. 3. Over a wide range of spatial frequencies the contrast threshold of a grating is determined only by the amplitude of the fundamental Fourier component of its wave form. 4. Gratings of complex wave form cannot be distinguished from sine‐wave gratings until their contrast has been raised to a level at which the higher harmonic components reach their independent threshold. 5. These findings can be explained by the existence within the nervous system of linearly operating independent mechanisms selectively sensitive to limited ranges of spatial frequencies.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
