Fourier’s theorem is used fairly extensively to design and simplify psychophysical experiments. Consequently, It is useful to understand some of the basic ideas behind it. Fourier theory states that any visual stimulus in space or time can be expressed as a sum of a series of spatial and temporal sinusoids. In the spatial “domain”, these are sinusoidal variations in brightness across the image. For example, the sinusoidal pattern shown below can be captured in a single Fourier term that encodes… Expand
