We illustrate the use of Non-Uniform Fast Fourier Transform (NUFFT) routines in "complex" (i.e., amplitude and phase) and phaseless Near-Field/Far-Field transformations. These routines result computationally very convenient when non-regular field sampling prevents the use of standard FFTs, as in the case of a plane-polar acquisition geometry. Numerical and experimental results show the effectiveness of the algorithms under such a scanning scheme.

Abstract
We illustrate the use of Non-Uniform Fast Fourier Transform (NUFFT) routines in "complex" (i.e., amplitude and phase) and phaseless Near-Field/Far-Field transformations. These routines result computationally very convenient when non-regular field sampling prevents the use of standard FFTs, as in the case of a plane-polar acquisition geometry. Numerical and experimental results show the effectiveness of the algorithms under such a scanning scheme.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
