    So far, we have discussed Fourier transformations involving one-dimensional functions. Of course, in studying imaging, the concept must be generalized to 2D and 3D functions. For example, diffraction and 2D image formation are treated efficiently via 2D Fourier transforms, while light scattering …

    Often, experiments involve light beams. A light beam can be defined as a distribution of field that fulfills the approximation in Eq. 20, i.e. is characterized by a dominant wave vector component, k(z) >> k(x) , k(y) . A beam is, therefore, the spatial equivalent of quasimonochromatic light, …
