the number of repeating elements in a pattern per unit distance. In a simple pattern of alternating black and white vertical bars (an example of a square-wave grating), the spatial frequency is the number of pairs of black and white bars per degree of visual angle, usually expressed as cycles per degree (cpd). See also contrast sensitivity.
