A Fourier transform is a form of mathematical operation that analyses data as a function of frequency (for example a spectrum is a form of Fourier transform). It can also be used to provide an analysis of the spatial distribution of objects in an image and extract pattern-based information that might not be obvious from a baseline's perception of the basic image.
In the early Interplanetary Age a number of groups, wanting to gain increased insight into a number of tricky theoretical and technical problems and the advantages that accrued from doing so, developed a set of mental enhancements that allowed them to perceive the Fourier transform of what they were seeing 'in parallel' with their normal visual perception. This did indeed allow them to easily perceive things hidden from those with merely baseline-type visual perception.
As such these modifications were quite successful, diversifying into a number of types based on the exact techniques used in the Fourier transforms, and becoming known, as a group, as the Fourier enhancements. These were one of a number of mathematical and perceptive modifications that were developed during this time period.
Over the years the various versions of the Fourier enhancements have spread across Terragens space. Both physical and virtual entities have had the enhancement made permanent, and various sub-clades of the overall Fourier group have come to be found everywhere. Most of those who originally acquired the trait were researchers of various kinds, but it is now found in entities from all walks of life. In particular, as far as it is known, all higher toposophic entities include the enhancement or something very like it.
Fourier researchers have, over the millennia, provided a number of significant insights into various fields where their enhancement gives them an advantage, and transcended to higher toposophic levels at a somewhat higher than average rate.
