{"version":"1.0","type":"link","title":"Spatial frequency - Newikis","description":"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.","provider_name":"Newikis","provider_url":"https://newikis.com","cache_age":86400,"thumbnail_url":"https://upload.wikimedia.org/wikipedia/commons/a/a6/Multiburst.jpg","thumbnail_width":640,"thumbnail_height":480}
