Introduction Two … WitrynaThe Hermite–Gaussians form a complete and orthonormal set in [42]. The Hermite–Gaussian functions are well known to be the eigenfunctions of the Fourier transform operator, as will also be seen below. We begin with the defining differential equation of the Her-mite–Gaussians: (4) It can be shown that the Hermite–Gaussian …
