Fourier spectrum of radially periodic images
Although the spectrum of radially periodic images is often expressed in terms of finite or infinite series of Bessel functions, such expressions do not clearly reveal the exact impulsive structure of the spectrum. An alternative Fourier decomposition of radially periodic images, in terms of circular cosine functions, is presented, and its significant advantages are shown. It is shown that the F...
متن کاملFourier spectra of radially periodic images with a non-symmetric radial period
It has been previously shown that a radially periodic image having a symmetric radial period can be decomposed into a circular Fourier series of circular cosine functions with radial frequencies of f = 1/T , 2/T , . . . , and that its Fourier spectrum consists of a series of half-order derivative impulse rings with radii f = n/T (which are the Fourier transforms of the circular cosines in the s...
متن کاملOn the spectrum of two-dimensional Schrödinger operators with spherically symmetric, radially periodic magnetic fields
We investigate the spectrum of the two-dimensional Schrödinger operator H = @ @x ia1(x; y) 2 @ @y ia2(x; y) 2 + V (x; y), where the magnetic field B(x; y) = @ @x a2 @ @y a1 and the electric potential V are spherically symmetric, i.e., B(x; y) = b(r), r = px2 + y2, and b is p-periodic, similarly for V . By considering two different gauges we get the following results: In case R p 0 b(s) ds = 0 t...
متن کاملSPECTRUM OF THE FOURIER-STIELTJES ALGEBRA OF A SEMIGROUP
For a unital foundation topological *-semigroup S whose representations separate points of S, we show that the spectrum of the Fourier-Stieltjes algebra B(S) is a compact semitopological semigroup. We also calculate B(S) for several examples of S.
متن کاملPolar Fourier transforms of radially sampled NMR data.
Radial sampling of the NMR time domain has recently been introduced to speed up data collection significantly. Here, we show that radially sampled data can be processed directly using Fourier transforms in polar coordinates. We present a comprehensive theoretical analysis of the discrete polar Fourier transform, and derive the consequences of its application to radially sampled data using linea...
