title: Perspective projections in the space-frequency plane and fractional Fourier transforms.
abstract: Perspective projections in the space-frequency plane are analyzed, and it is shown that under certain conditions they can be approximately modeled in terms of the fractional Fourier transform. The region of validity of the approximation is examined. Numerical examples are presented.
