For a scalar field the Fourier transform of is a function of the spatial wave number, and the temporal frequency.

Findings show that as spatial frequency is increased, sensitivity to temporal frequency decreases.

It is also referred to as temporal frequency, which emphasizes the contrast to spatial frequency.

Spatial frequency is analogous to temporal frequency, but the time axis is replaced by one or more spatial displacement axes.

Wavenumber, k, sometimes means the spatial frequency analogue of angular temporal frequency.

Spatial frequency; also sometimes temporal frequency.

The orthogonal motion was of a circular grating contracting so as to have the same temporal frequency as the radial grating.

Their temporal resolution, which is fair, refers to the highest temporal frequency with which the cell can follow reversals of stimulus intensity within the receptive field.

Fourier transforms are not limited to functions of time, and temporal frequencies.

In optics, smear is used to refer to motion that has low temporal frequency relative to the integration/exposure time.
