The spatial frequency refers to how many complete periods the signal goes through for a given unit of distance (eg. cylcles/m) while the temporal frequency refers to how many complete periods the signal goes through for a given unit of time (eg. cyles/s or Hz).

What is meant by spatial frequency?
The spatial frequency is defined as line pairs per angular extent of the target, and the phase specifies the relative location of the target image to the detector array raster. From: Encyclopedia of Modern Optics, 2005.
What is meant by spatial and temporal?
Spatial refers to space. Temporal refers to time. Spatiotemporal, or spatial temporal, is used in data analysis when data is collected across both space and time.
What is an example of spatial frequency?
Spatial frequency describes the periodic distributions of light and dark in an image. High spatial frequencies correspond to features such as sharp edges and fine details, whereas low spatial frequencies correspond to features such as global shape.
What is spatial frequency in radiography?
Spatial frequency is generally expressed as cycles, or line pairs, per millimeter (lp/mm) in analog environments, but for digital systems, cycles per pixel (c/p) is more appropriate where sensor sizes vary from one detector to another.
