In mathematics, physics, and engineering, spatial frequency is a characteristic of any structure that is periodic across position in space . The spatial frequency is a measure of how often sinusoidal components (as determined by the Fourier transform) of the structure repeat per unit of distance.

“Spatial frequency” refers to the number of pairs of bars imaged within a given distance on the retina . One-third of a millimeter is a convenient unit of retinal distance because an image this size is said to subtend one degree of visual angle on the retina.

In mathematics, physics, and engineering, spatial frequency is a characteristic of any structure that is periodic across position in space. The spatial frequency is a measure of how often sinusoidal components (as determined by the Fourier transform) of the structure repeat per unit of distance.
Read moreDoes spatial frequency affect visual acuity?
The loss of sensitivity in the mid to high spatial frequencies was profound during abnormal visual development, with increased deprivation leading to further contrast losses . Not only will certain disease/disorders of the eye reduce visual acuity, contrast sensitivity will also be affected (18).
