Abstract
Perspective projections in the space-frequency plane are analyzed, and it is shown that under certain conditions they can he approximately modeled in terms of the fractional Fourier transform, The region of validity of the approximation is examined. Numerical examples are presented. (C) 2000 Optical Society of America
