The fractional Fourier transform and quadratic field magnetic resonance imaging

The fractional Fourier transform and quadratic field magnetic resonance imaging

... The fractional Fourier transform (FrFT) is revisited in the framework of strongly continuous periodic semigroups to restate known results and to explore new properties of the FrFT. We then show how the FrFT can be used ...
