Two-Dimensional Fourier Transform
2021In this chapter, we present elements for calculating and plotting discrete two-dimensional Fourier transforms. Figure 17-1 provides two screenshots from an Android cell phone. The one on the left shows a rectangular, two-dimensional spatial-function. The right screenshot shows the corresponding discrete Fourier transform obtained using this program.

Two-dimensional Fourier transform rheology
Journal of Rheology, 2001A two-dimensional Fourier transformation (FT) rheology experiment is presented that separates the relaxation dynamics of different contributions to the stress relaxation, here specifically for entangled polymers. This experiment has the overall form of discrete large amplitude oscillations and consists of multiple step shear experiments.

The Two-Dimensional Clifford-Fourier Transform
Journal of Mathematical Imaging and Vision, 2006As well known the classical uni-dimensional Fourier transform is a very powerful tool which is very useful in Analysis as well as in many other areas of mathematics. It is also used in many practical applications like information storage procedures, for instance.
